The present invention relates to a multi-purpose button switch cover, and four functions such as malfunction prevention function, instantaneous connection function, continuous connection function, and line control alarm operation function are combined in one component and are selected according to the purpose of the button switch suitable for each function. As it can be used as a counter, Utility Model Registration No. 30110 of the present invention is an improved design of the "button for preventing malfunction".

Utility Model Registration No. 30110 can only exhibit the independent idle function, which is a shortcoming of the number of buttons. Therefore, when switching the continuous operation switch to the momentary operation switch, two switching switches must be separately installed or the switch must be replaced at all. In order to improve the point, as shown in FIGS. 1 and 2, the cover plate 20 is installed to be opened and closed on the front of the switch body 10 in which the push button 10 'is installed, and the switch The cover body 30 is installed on one side of the front part of the main body 10 so as to be opened and closed, and the cover body 30 is provided with a stop button 40 formed on the plywood 30 'which is in contact with the push button 10'. In case of non-operation or instant connection, the cover plate 20 can be opened and closed to prevent malfunction or press the push button 10 'to be used for instant connection. Open the plate 20 and cover body ( The operation method is complicated to respond quickly according to the situation because it requires three steps of operation to close the 30 and then press the stop button 40, the person for fixing the lid 30 on the switch body 10 The mounting means 50 should be provided, and the stop button 40 itself should be separately provided in addition to the push button, and as the structure of the whole becomes complicated, the manufacturing cost is high and it is inconvenient to use.

The present invention has been devised in view of this point, and a cover having a malfunction prevention and continuous pressing means and a line controlled alarm operation means is separately formed from the switch body to selectively respond to various types of button switches according to the respective applications. It is possible to use, but in particular, the configuration and operation method of the pressing means can be simplified and simplified, and the manufacturing cost can be drastically reduced, and the malfunction preventing means is automatically released during the operation of the pressing means. It is designed to be faster and to provide line-controlled alarms with simple operation.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 3, the cover 1 has a circular or rectangular box shape in which a lid 2 integrally formed with the square turning hole 5 is coupled and covered by hinge hinges 6 at both ends thereof. An insertion hole 1 'is formed, and the pressing bar 3 having the pressing portion 3', the handle protrusion 7 and the pin hole 8 has a square having hinge protrusions 6 'at both ends on one side thereof. Rotating opening (5 ') is integrally formed to be installed so as to rotate, and on the other side of the upper end forming the rubbing groove (4) protruding inward rubbing projection (4') on both sides of the pressing stand (3) The thickness (a) and the height (b) of the hanging groove (4) are the same, and at the rear and side ends of the cover body (1), the coal pieces (9) and (9 ') are respectively raised upward integrally with the lid (2) and It is the structure that the outer surface of the square rotation hole 5, 5 'of the press bar 3 is faced, respectively.

Reference numeral 10 is a switch body, 10 'is a push button, 11 is a packing, 12 is a coupling nut, 13 is an alarm line, 14 is a coupling pin, 15 is a clip.

According to the present invention configured as described above, as shown in FIG. 4, the switch body 10 is inserted through the through hole 1 ′ of the bottom of the cover body 1 so that the push button 10 ′ is placed in the cover body 1. After it is built in, it is used by screwing as a coupling nut 12 through the packing 11 at the bottom of the cover body. The switch is connected to a contact every time a button is pressed or a button is pressed once. If the state is maintained and the button is pressed again, the contact is disconnected or the reverse function can be used selectively.

FIG. 5 shows that the lid 2 is opened while the cover body 1 and the switch body 10 are coupled to each other so that the built-in push button 10 ′ is blocked from the outside, thereby preventing malfunction. Here, the inner surface of the pressing portion 3 'of the presser 3 installed on one side of the cover body 1 comes into contact with the bottom surface of the lid 2, and in such a state, the pusher is desired to use the switch. When the button 10 'is pressed, the pressing stand 3 is rotated in the direction of the arrow as shown in 6a and b. When the bottom surface of the lid 2 is pressed, the pressing portion 3' of the pressing stand 3 is in contact with it. Sliding outward on the inner side gradually rotates up around the hinge portion consisting of a square turning hole (5) and the hinge projection (6) is opened. At this time, the upper body piece 9 of the cover body 1 facing the outer side of the square pivot 5 is pushed outward and has elasticity, and the rotational angle of the lid 2 is 70-80 °, that is, vertical When it reaches to the state just before being built, the square turning hole 5 is spun by spontaneous force by the repulsive force of this piece 9, and the lid 2 is set up in a vertical state and at the same time stops rotating in that state.

Therefore, the lid 2 is fully open and the push button 10 'exposed to the hand is used for simple pressing purposes, or the push button 10' is continuously rotated so that the push button 10 'is pressed against the pressing portion ( 3 '), it can be used for a pressing purpose by being clamped in the latch groove 4 which has the inward latch projection 4' of the cover body 1 side in the state pressed by 3 ').

In the opposite operation, when the push button 10 'is pressed, the contact is disconnected, and when the pressed state is released, the pusher 3 is closed as shown in FIG. The lid 2 is opened in the fixed groove 4 on the cover 1 to block the presser bar from the outside, thereby preventing malfunction, and the handle protrusion 7 of the presser 3 is used. When the presser is displaced in the recess groove 4 and rotates the presser in the opposite direction to the above, the lid 2 is opened by the reverse action, and the push button 10 'that is pressed is released to make contact contact. Since the thickness (a) of the base (3) and the height (b) of the hanging groove (4) is the same, there is no fear of foreign matter penetration when the lid is opened, and the bottom of the lid and the upper surface of the presser bar are in contact with each other without a gap in the opened state. Prevent the associated operating point from being delayed by the gap. It is suitable for applications such as burglar and fire alarms work that requires a quick response.

Accordingly, as shown in FIG. 8, by inserting the engaging pin 14 connected to the alarm line 13 to the pin hole 8 of the pusher 3, the alarm line is pulled and fixed with the clip 15 to be alerted by an external intruder. When the line 13 is pulled further, the pusher 3 into which the engagement pin 14 is fitted in the pin hole 8 is released from the recess 4 in the cover body 1, and the alarm is activated as the switch is connected. It is possible to configure a line-controlled alarm operation system.

Here, the presser (3) also has a bullet piece (9 ') facing the outer side of the rectangular turning hole (5'), like the lid (2), so that the hinge projection (6 ') is made at any rotation point by its repulsive force Rotation is automatically performed from the starting point.

Meanwhile, as shown in FIG. 8, a downward protrusion 1 ″ is formed on the outer circumferential surface of the through hole 1 ′ at the bottom of the guide groove 4 on the cover body 1 to the packing 11 when the switch body 10 is engaged with the switch body 10. In this case, the width C of the grooved groove 4 is in a normal state (shown in FIG. 10A) in the loose state according to the tightening state of the coupling nut 12, and in the tight state, the width C is narrowed (the 10b) to adjust the locking state of the pusher 3.

As described above, the present invention can be selectively used for various kinds of button switches according to each use, and can exhibit various functions such as instantaneous connection function, continuous connection function, line controlled alarm operation function, and malfunction prevention function. The simple construction and operation method can greatly reduce the manufacturing cost and at the same time, the use is very convenient.
