The edge of the external shell 6a and the circuit board 10 clamp the two sides 16a, 16a of the elastic member 16 .

And, the elastic movable body 17 of the control switch device 1 is formed on the elastic member 16, and at the same time, the respective operating parts corresponding to the sleep button switch 2, the mode button switch 3, the A button switch 4, and the B button switch 5 are formed. Sleep button 18, mode button 19, A button 20, B button 21, respectively form conductive parts 22, 23, 24, 25 on the respective lower surfaces of the sleep button 18, mode button 19, A button 20, B button 21 , the tops of the above-mentioned sleep button 18, mode button 19, A button 20, B button 21 protrude upward from the hole of the outer casing 6a of the casing 6, when the sleep button 18, mode button 19, A button 20, B button 21 are pressed When the top of the sleep button 18, mode button 19, A button 20, B button 21, the thin peripheral walls 27, 28, 29, 30 are elastically deformed, and the conductive parts 22, 23, 24, 25 are in contact with the electrical contacts. The points 12, 13, 14, and 15 are in contact, and the electrical contacts 12, 13, 14, and 15 are switched to an on state.

However, in the elastic movable body 17 of the elastic member 16, the conductive portions 31a, 31b, 31c, and 31d are formed directly above the four pairs of electrical contacts 11a, 11b, 11c, and 11d. , 31b, 31c, 31d to form a thin outer peripheral wall 32 below, and form a guide hole 33 in the center of the elastic movable body 17, and insert a stop made of hard plastic to become a fulcrum member in the guide hole 33 from the bottom to the top. Actuator 34.

The length L of the above-mentioned stopper 34 is set to be shorter than the thickness D of the elastic movable body 17 in the natural placement state, and the lower part 34a of the stopper 34 is formed in a flange shape, and at the same time, the upper and lower sides of the stopper 34 The end is formed into a gentle curved shape.

Above the elastic movable body 17 of the elastic member 16 , an opening 35 is formed in the outer casing 6 a of the case 6 , and the key top 36 is fitted into the opening 35 from the bottom to the top and placed on the elastic movable body 17 .

A cross-shaped protruding portion 37 is formed on the top of the key top 36, front, rear, left, and right, and at the same time, a flange portion 38 is formed on the lower peripheral portion of the key top 36, and a notch 39 is formed on the flange portion 38 as shown in FIG. 7 . , the notch 39 is interlocked with the locking part 40 (referring to Fig. 4 to Fig. 6 ) formed on the opening 35 of the outer shell 6a of the shell 6, and the key top 36 can be tilted forward, backward, left, or right in any direction, and will not be vertical. The axis rotates as the center.

As shown in Fig. 9, Fig. 11 and Fig. 12, in the center of the lower part of the key top 36, there remains a cross-shaped reinforcing rib 41 directly below the protruding part 37 to form four concave surfaces 42, and each reinforcing rib 41 is located in each Directly above the conductive part 31 , when the key top 36 is pressed obliquely, any one of the reinforcing ribs 41 presses the conductive part 31 directly below it to the electrical contact 11 on the circuit board 10 through the elastic movable body 17 .

As shown in FIG. 15, the space on the circuit board 10 surrounded by the thin peripheral wall 32 below the elastic movable body 17 and the sleep button 18 and the mode button are formed on the lower surface of the above-mentioned elastic member 16. 19. A communication groove 43 communicating with the space on the circuit board 10 surrounded by the thin peripheral walls 27, 28, 29, 30 below the A button 20 and B button 21; a communication groove 44 connecting these spaces with the outside , when the elastic movable body 17, sleep button 18, mode button 19, A button 20, B button 21 are pressed, the air enclosed in these spaces can flow freely to other spaces or to the outside.

Because the embodiment shown in Fig. 1 to Fig. 19 constitutes as above, when the sleep button 18, mode button 19, A button switch 2, mode button switch 3, A button switch 4, B button switch 5 are pressed downwards, When any one of the button 20 and the B button 21 is selected, one of the thin outer peripheral walls 27, 28, 29, 30 below bends and deforms downward, and one of the conductive parts 22, 23, 24, 25 is the same as the electrical contact 12. , 13, 14, and 15 are in contact, and one of the sleep button switch 2, mode button switch 3, A button switch 4, and B button switch 5 is turned on.

When any one of the protruding parts 37 (for example, 37a) in the key top 36 of the control switch device 1 is pressed, as shown in FIG. The lower surface of the outer casing 6a near the opening 35 adjacent to the protruding portion 37c is engaged with the lower surface of the outer shell 6a, and the key top 36 is inclined to the right with this as the center, and the lower surface of the key top 36 is in contact with the apex of the stopper 34. , then, the key top 36 moves to the right, as shown in Figure 6, the peripheral surface of the key top 36 adjacent to the protruding part 37a is in contact with the opening 35, and the conductive part 31a directly below the protruding part 37a is pressed to On the electrical contact 11a on the wiring board 10, the electrical contact 11a is brought into a conduction state.

In this way, when the protruding portion 37a is pressed down, at first, the flange portion 38c adjacent to the protruding portion 37c on the opposite side engages with the lower surface of the outer shell 6a near the opening 35, and the thickness of the lower part directly below the protruding portion 37a is thinner. The outer peripheral wall 32a of the elastic deformation occurs, and at the same time, the key top 36 is inclined with the snap point as the center, and the lower surface of the key top 36 contacts the top of the stopper 34, so the contact impact force will not directly act on the circuit board. 10 on the upper surface, then noise and vibration are less likely to occur.

After the lower surface of the key top 36 touches the top of the stopper 34, since the lower surface of the key top 36 slides over the top of the stopper 34, the lower end of the stopper 34 will not rub against the upper surface of the circuit board 10. , so as to avoid friction on the upper surface of the circuit board 10 and prevent damage to the circuit board 10 .

And, when the key top 36 is pressed down, the guide hole 33 provided on the wall thickness portion 45 of the elastic movable body 17 slides in contact with the outer periphery of the stopper 34, and therefore, the pressing force of the key top 36 is controlled by the key top 36. Sliding is absorbed, and the above-mentioned impact force is alleviated.

The key top 36 is pressed upwards by the elastic force of the elastic movable body 17, and the flange portion 38 of the key top 36 is engaged with the opening 35 of the casing 6. Therefore, the outer shell 6a of the casing 6 is relatively to the circuit board 10. The spacing does not need to be high precision, and placing the key top 36 on the elastic movable body 17 of the elastic member 16 can integrate the outer shell 6a and the inner shell 6b of the shell 6, and as a result, significantly improves the Processability, assembly, and can reduce costs.

Since the upper and lower ends of the stopper 34 are gently curved, the key top 36 can be smoothly inclined in any direction.

And since the lower surface of the rib 41 of the key top 36 and the upper surface of the elastic movable body 17 are all planar, useless power will not be applied on the elastic movable body 17 in the placed state, thereby improving the Durability of the elastic movable body 17.

And, since all the conductive parts 31a, 31b, 31c, 31d of the elastic movable body 17 are surrounded by a thin peripheral wall 32 below, these conductive parts 31a, 31b, 31c, 31d will not be polluted by dust etc., and Miniaturization of the elastic movable body 17 can be realized.

On the circuit board 10, the spaces surrounded by the thin outer peripheral walls 27, 28, 29, 30, 32 below the outer circumferences of the conductive parts 22, 23, 24, 25, 31 communicate with each other through the communication groove 43, and at the same time , communicate with the outside by the communication groove 44, therefore, in the operation of control switch device 1, sleep button switch 2, mode button switch 3, A button switch 4, B button switch 5, even if these spaces shrink, the space in these spaces Air can flow freely, and keep the inner pressure of these spaces constant, then the action of control switch device 1, sleep button switch 2, mode button switch 3, A button switch 4, B button switch 5 is carried out smoothly.

Furthermore, for example, when the space between the protruding portions 37a, 37b of the key top 36 is pressed, the key top 36 is inclined in that direction, and the electrical contacts 11a, 11b are simultaneously turned on.

Since the stopper 34 as a fulcrum member is made of hard plastic, it has moderate hardness and inherent lubricity, and is inexpensive. The stopper 34 may also be made of metal, in which case the stopper 34 can slide relative to the circuit board 10 and the wear resistance can be improved.

Since the embodiment shown in FIGS. 20 to 35 has the above-mentioned structure, by the elastic force of the thin outer peripheral wall 73 below the elastic movable body 70, the pressing thickness portion 78 directly above the conductive portion 72 is pressed downward from the bottom. The pressing member 67 pressing the key top 62 above receives its reaction force, and the receiving part 63 of the key top 62 contacts the support protrusion 61 of the outer shell 59a, and as a result, as shown in FIG. 25, the key top 62 is supported. .

As shown in Figure 26, when the protruding portion 64 of the key top 62 is pressed down, the key top 62 descends, and the pivot concave surface 66 of the key top 62 is engaged with the upper end of the pivot stopper 77 to support, so that The upper end of the pivot stopper 77 is centered, the key top 62 is inclined, and the pressing part 67 directly below the pressed protruding part 64 crushes the pressing part 78 of the elastic movable body 70, and the conductive part 72 presses down. To the electrical contact 69, the electrical contact 69 becomes a connected state.

The operating force applied to the key top 62 is transmitted to the circuit board 68 through the pivot concave surface 66 and the pivot stopper 77 of the key top 62. Since the contact area between the lower surface of the pivot stopper 77 and the circuit board 68 is enlarged, A large force is not locally applied to the wiring board 68, and as a result, the wiring board 68 is neither worn nor damaged.

The pressing part 78 of the elastic movable body 70, as shown in FIG. , and be crushed, therefore, the conductive part 72 below it can be in contact with the electrical contact 69 of the circuit board 68, and has improved the reliability of switch-on.

Moreover, the elastic movable body 70 is in contact with the inner circumference of the peripheral upstanding piece 71, and is pressed against the upper surface of the circuit board 68 by the reinforcing rib 59b of the outer shell 59a. Therefore, the elastic movable body 70 is always stable, and While maintaining the predetermined position of the circuit board 68, the space between the elastic movable body 70 and the circuit board 68 is isolated from the outside except for the communication groove 75, thereby suppressing the intrusion of dust and the like.

The upper end portion of the pivot stopper 77 is formed in a substantially hemispherical shape, and at the same time, the pivot concave surface 66 of the key top 62 is formed in a hemisphere having a curvature radius slightly larger than that of the upper end hemispherical surface of the pivot stopper 77. Shaped concave surface, thus, relative to the pivot stopper 77, the key top 62 will not deviate its pivot position, but keep stable, at the same time, at the upper hemisphere upper part of the pivot stopper 77 and the key top 62 There is no large frictional force between the hemispherical pivot concave surfaces 66, and as a result, the key top 62 can be tilted stably and lightly.

Since the pivot stopper 77 is made of metal, it has excellent durability.

The shell 6, circuit board 10, electrical contact 11, elastic member 16 and elastic movable body 17 in 1 are roughly the same structure as the shell 82, circuit board 83, electrical contact 84, elastic member 85 and elastic movable body 86.

In the elastic movable body 86 of the elastic member 85 made of silicone rubber, it is located directly above the four pairs of electrical contacts 84a, 84b, 84c, and 84d (the electrical contacts 84d are not shown). , forming a conductive portion 87a, a conductive portion 87b, a conductive portion 87c, and a conductive portion 87d (the conductive portion 87d is not shown), which are softer than the elastic movable body 86, and forming a thin peripheral wall 88 below to completely surround these conductive portions 87a, conductive portion 87b, conductive portion 87c, and conductive portion 87d. An insertion hole 89 is formed in the center of the elastic movable body 86. The insertion hole 89 has self-lubricating properties and is slightly softer than the key top 92. A fulcrum made of silicone resin The member 90 is integrally fitted with an adhesive, and the lower end portion 90a of the fulcrum member 90 is formed in a substantially hemispherical shape.

Moreover, a cross-shaped protruding portion 93 is formed on the front, rear, left, and right sides of the top of the key top 92, and at the same time, a flange portion 94 is formed on the lower peripheral portion of the key top 92, and the flange portion 94 is formed by the elastic restoring force of the elastic movable body 86. The portion 94 is engaged with the lower end portion 91a of the opening 91, and in this engaged state, the hemispherical lower end portion 90a of the fulcrum member 90 is separated from the upper surface of the circuit board 83 by a predetermined distance.

A communication groove 95 is formed on the elastic member 85 so as to communicate with the space on the circuit board 83 surrounded by the thin peripheral wall 88 below or the outside.

The key top 92 is formed solid, but may also be formed the same as the key top 36 in the control switch device 1 shown in FIGS. 1 to 19 .

Since the embodiment shown in FIG. 36 has the above-mentioned structure, when any one of the protruding parts 93 (such as the protruding part 93c) of the key top 92 of the control switch device 81 is pressed, the key top 92 is centered on its buckling part. Inclined so that the flange portion 94 is engaged with the lower end portion 91a of the opening 91 on the side opposite to the pressed portion so that the pressed protruding portion 93 descends, and at the same time, moves in the direction of the pressed side, the fulcrum member After the lower end 90a of 90 touches the upper surface of the circuit board 83, the key top 92 is further inclined to the above-mentioned inclination direction, and the conductive part 87c directly below the pressed protruding part 93c is pressed onto the electrical contact 84c of the circuit board 83. , the electrical contact 84c becomes conductive.

In this way, when the protruding portion 93c is pressed down, at first, the flange portion 94a adjacent to the protruding portion 93a on the opposite side is engaged with the lower end portion 91a of the opening 91, and the thin outer peripheral wall 88c directly below the protruding portion 93a is At the same time, the key top 92 inclines around the buckling point, and the lower end 90a of the fulcrum member 90 integrated with the elastic movable body 86 is in contact with the circuit board 83. Therefore, the contact impact force is relatively soft.

Moreover, the fulcrum member 90 is harder than the elastic movable body 86 of the elastic member 85, and the fulcrum member 90 bears the pressing force of the key top 92. Therefore, the lower surface of the elastic movable body 86 is not buried very deeply, and the adjacent two Each conductive portion 87 is in contact with the electrical contact 84 on the circuit board 83 at the same time, but the situation that more than three conductive portions 87 are in contact with the electrical contact 84 on the circuit board 83 at the same time will not occur.

Since the fulcrum member 90 has self-lubricating properties, the lower end portion 90a of the fulcrum member 90 can slide gently over the upper surface of the circuit board 83 to prevent the upper surface of the circuit board 83 from being worn.

Furthermore, since the elastic movable body 86 of the elastic member 85 and the fulcrum member 90 are integrally formed in advance, the assemblability of the control switch device 81 is improved.
