Description

[Detailed description of the invention] The present invention relates to a push button switch device, and its purpose is to make the button/button switch extremely simple in configuration, and to improve the operating feeling by reducing the operating stroke. be.

Conventional push-button switches combine a push-button switch with a complicated locking mechanism, as seen in the pause switch section of a tape recorder, and are difficult to assemble due to the large number of parts, making them expensive. there were.

The present invention eliminates these conventional drawbacks,
Examples thereof will be described below with reference to the drawings.

In the figure, 1 is a printed circuit board that serves as a base, and this board 1
A holding member 3 made of synthetic resin is attached with pins 2 to.

This holding member 3 has a pressing part 6 that transmits the movement of the protrusion 5 protruding from the lower surface of the push button 4, and a resilient part 7 and an engaging part 8 that enable the pressing part 6 to move in the vertical direction.

Reference numeral 9 denotes a conductive member made of conductive rubber or the like that moves in conjunction with the movement of the pressing portion 6, and is fused to the inside of the pressing portion 6 of the holding member 3, and includes a claw portion that engages with the retaining portion 8. It has 10.

11 is a pair of copper foils printed on one side of the printed circuit board 1, and when the pair of copper foils 11 are short-circuited by the conductive member 9, an electric signal flows between the pair of copper foils. It has become.

The operation of the above embodiment will now be explained.

First, in FIG. 1, the pressing part 6 is biased by the elastic part 7 so that the conductive member 9 is in a position away from the copper foil 11, and the electrical signal applied to the copper foil 11 is cut off.

Next, as shown in FIG. 2, by pushing the pressing part 6 in the direction of arrow A, the elastic part 7 is deformed, and the claw part 10 of the conductive member 9 engages with the engaging part 8, and is held in that state. .

At this time, the conductive member 9 comes into contact with the contacts 11, 11, and an electrical signal is transmitted.

Next, as shown in FIG. 3, by further pushing the pressing part 6 in the direction A, the pressing part 6 and the conductive member 9 are deformed, and the claw part 10 retreats inward to engage with the engaging part 8. is released.

After release, when you release your finger from the pressing part 6, the pressing part 6 will move to the elastic part 7.
Due to the urging force of , it returns in the direction of arrow B to the state shown in FIG.

At this time, the electrical signal on the copper foil 11 is cut off again.

As described above, according to the present invention, it is possible to realize a push-button switch device that can self-retain when connected without using metal parts. Excellent operability, with little change, and since the self-holding mechanism is an engagement between engaging parts protruding from the elastic body, there is no wear, and there is no metallic engagement or release noise. is possible.
