Abstract

The push button type switch includes a box having a button movably inserted into the box, and the movable member has a U-shaped guide member having an end that engages a recess area enclosed in the button. The movable member is connected to a bimetal plate or the like so that the movable member can move when overridden. When the movable member moves, the leg portion of the U-shaped guide member moves within the inner circumferential surface of the recessed region to move the button up.

Description

CONTROL DEVICE FOR A PUSH-BUTTON TYPE SWITCH}

The present invention has a movable member, and the movable member has a guide member elongated and the guide member is kept movable in the polygonal recessed area in the button, so that the movable member moves together with the movable member when the movable member moves. It is related to a push button switch.

Conventional switches have bimetal plates that deform when the current is overridden to separate the two contact ends to open the circuit. Switches of this type are disclosed in US Pat. No. 5,223,813, US Pat. No. 4,937,548, US Pat. No. 4,937,548 and US Pat. No. 5,451,729. These switches have a lever-shaped button that can actuate the switch at any end. However, the large support points of the buttons wear out over time and cause a slow response.

Another push-button switch has been developed, with the buttons moving up and down, and no leverage support is provided. The position of the button allows the user to easily check the state of the button. This type of switch does not have the proper mechanism to cooperate with the button to solve the override situation. In other words, since the direction of the buttons is up and down, the size of the mechanism becomes large, and therefore difficult to properly accommodate in the switch box.

It is an object of the present invention to provide a control device of a push button type switch that can change a horizontal operation to a vertical operation to operate a button.

According to one aspect of the present invention, there is provided a push button type switch comprising a box having a button movably inserted in an open top of the box. The tubular member is formed long at the bottom of the button, and the spring is biased to one side between the tubular member and the box. The recessed region is formed on the surface of the tubular member and is defined by the polygonal inner circumferential surface. The movable member has two slots, and two rods are movably received in the two slots. The guide member is formed long in the movable member and movably engages the recessed region.

An object of the present invention is a push button having a movable member with a guide member movably coupled with a polygonal recess so that the movable member can move upwards to open the circuit when the movable member is moved by, for example, a bimetal plate. To provide a switch.

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

As shown in Figures 1 to 3, the push-button switch according to the present invention includes a box (2), which is a button (movably inserted into the open top 21 of the box 2) 1) is provided. The tubular member 11 is formed long in the lower part of the button 1, and a hole is formed in the lower part of the tubular member 11, and the one end part of the spring 14 is accommodated. The other end of the spring 14 is in contact with the inside of the box 1. The tongue-like member 13 is formed long in the lower part of the button 1, and has the inclined surface. A recess region 12 is formed on the surface of the tubular member 11, and the recess region 12 has a polygonal inner circumferential surface. The central member 121 is positioned at the center of the recessed region 12, and the recessed portion 1210 is formed above the central member 12. The triangular plate 122 is formed long on the inner circumferential surface of the recess region 12 and is located on the recessed portion 1210 of the central member 12. Two slots 20 are formed below the box 2 so that two terminal plates (not shown) are inserted into the two slots 20. Two rods 217 and 2170 are formed long inside the box 20, respectively. The board 22 is formed long inside the box 20, and a hole 26 is formed in the surface of the board 22.

Two slots 42 and 43 are formed in the movable member 4, and two rods 27 and 270 are movably received in these two slots 42 and 43. The pressing end 44 is formed long at the end of the movable member 4. The U-shaped guide member 40 has a leg portion 41 that penetrates the hole 411 in the movable member 4 and is movably engaged with the recess region 12. The other leg portion 410 of the U-shaped guide member 40 is inserted into a hole 26 formed in the board 20. One end of the L-shaped spring 45 engages with the recess 211, and the other end of the L-shaped spring 45 pushes the U-shaped guide member 40 toward the recess region 12 of the button 1. .

When the circuit is in the open state, as shown in Fig. 3, the button 1 is located at the highest position by the spring 14, and the leg portion 41 is shown in the recess area (as shown in Fig. 6A). 12) at the lowest position.

As shown in Figs. 4 and 6B, when the button 1 is pressed and the circuit is closed, the leg portion 41 of the U-shaped guide member 40 moves counterclockwise. When the user releases the button 1, as shown in FIG. 6C, the button 1 moves slightly upward, the leg portion 41 is placed in the depression 1210, and the triangular plate 122 is centered. Located between the members 121. In this position, the leg portion 41 keeps the button 1 placed in the predetermined position as it is, and is not lifted up by the spring 14. When the button 1 is pressed again, the circuit is opened and the leg portion 41 moves as shown in Fig. 6D.

FIG. 5 shows that when the override 3 is applied, the pressing end 44 of the movable member 4 is pressed, and then the leg portion 410 of the U-shaped member 40 is in the position of FIG. 7A in FIG. 7B. This movement of the leg portion 41 in the recessed area 12 causes the button 1 to move up, and the leg portion 41 of the U-shaped member 40. Moves to the position shown in Fig. 7c.The force 3 is generated by, for example, a bimetal plate, which deforms when the current is overridden, thereby pushing the pressing end 4 to the left. The size of the switch box 2 can be greatly reduced, and the structure can be simplified.

FIG. 8 shows a state in which the guide member 41 'is elongated directly in the movable member 4, and the movable member 4 is still biased to one side by the L-shaped spring 45'.

While various embodiments of the present invention have been illustrated and described as described above, the present invention is not limited thereto, and various modifications and changes can be made without departing from the spirit and scope of the present invention.

The push-button switch of the present invention is in such a way that the button moves together with the movable member when the movable member moves, so that the override situation can be easily solved while taking a small structure.
