Abstract

PURPOSE:To prevent malfunction by switching and operating a contact of a switch body in a vertical direction on the side surface of an operational piece of a push button. CONSTITUTION:A pair of operational pieces 4 protruded in parallel from both ends of a push button 1 to the rear part in an integrated manner, form an operating part 4a tilted to the side of the inner surface of the point of both operational pieces 4, while a switch body 5 arranged in an opposed manner on the inner side of the operational piece 4, is provided with a contact 5a press- moved vertically by the operational surface 4a. When a push surface 1a is pressed and operated, the push button 1 is rotated around a shaft pin 3 as a fulcrum, and a contact 5a of another switch body 5 is switched and operated on the operational surface 4a of the operational piece 4. The switching operation can thus be carried out by pressing the contact 5a in a vertical direction which is a true direction for switching, by the operational surface 4a, and the switching operation without malfunction can thus be carried out.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a seesaw pushbutton device used in communication equipment and the like.

[Conventional technology]

FIG. 3 is a block diagram showing a conventional seesaw pushbutton device. In the figure, 1 is a seesaw-type pushbutton having two push surfaces 1a. It rotates in a shape.

Reference numeral 4 denotes a pair of operation pieces integrally projecting rearward from both ends of the push button 1, and 5 is a switch body disposed at a distance from the end faces of both operation pieces 4, which are supported by a base plate 6. be. 7 is a main board electrically connected to this board 6 via conductive leads 8.

The push button device configured as described above has one push surface 1a.
When pressed, the pushbutton 1 rotates around the shaft pin 3, and the operating piece 4 operates the contact 5a of one switch body 5 to transmit an electrical signal to the main base Fi7 via the conductive lead 8. be able to.

[Problems to be Solved by the Invention] Since the conventional seesaw push button device is configured as described above, when the switch is operated by the push button 1, the operating piece 4 contacts the contact point of the switch body 5 as shown in FIG. Since the switch 5a is operated in a direction different from its original operating direction, there is a problem in that the switch malfunctions. In addition, in order to arrange the switch body 5 near the operation piece 4, it is necessary to provide a board 6 separate from the main board 7.
There is also the problem that the number of parts increases because conductive leads 8 are required to electrically connect both substrates 6 and 7, and spacers are also required to insulate and hold the substrates 6.

This invention was made to solve the above-mentioned problems, and provides a seesaw push button device that can perform accurate switching operations, reduce the number of parts, simplify the configuration, and be manufactured at low cost. The purpose is to

[Means to solve the problem]

The seesaw pushbutton device according to the present invention is a pushbutton that is rotatably supported on a panel in a seesaw shape with a shaft pin as a fulcrum, and has a pair of operating pieces that protrude rearward in parallel while sandwiching the rotational shaft. and a switch body having contacts that are attached to the substrate and face the inner surfaces of the operating piece and are pressed in a vertical direction by the operating piece when the switch is operated.

[For production]

Since the seesaw pushbutton device according to the present invention is configured as described above, the operation piece can switch the contact point of the switch body in the vertical direction, which is the correct pressing direction, by the switch operation of the pushbutton.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. 1st
The figure is a configuration diagram of a seesaw push button device according to the present invention. In the figure, 1 is a no-saw push button having two push surfaces 1a on the surface, and a shaft pin 3 supported on a panel 2.
It rotates like a stack using the fulcrum as a fulcrum. Reference numeral 4 denotes a pair of operating pieces projecting rearwardly and parallel to each other from both ends of the push button 1, and forming an operating surface 4a that slopes toward the inner surface of the tips of both operating pieces 4. Reference numeral 5 denotes a switch body disposed on the inner side of the operation piece 4 to face each other, and includes a contact point 5a that is pressed in the vertical direction by the operation surface 4a. Reference numeral 6 denotes a board on which the switch body 5 is attached on both sides.

Since the seesaw push button device of the present invention is configured as described above, when one push surface 1a is pressed, the push button 1
rotates about the shaft pin 3 as a fulcrum, and the operation surface 4a of the operation piece 4
Then, the contact 5a of one switch body 5 is operated to switch. In this switching operation, the operation surface 4a presses the contact point 5a in the vertical direction, which is the original switch operation direction, as shown in FIG. 2, so that the switch operation can be performed without causing any malfunction. In addition, by using the above-mentioned push button device, the contact 5
The operation surface 4a of the operation piece 4 will not come off from the position a.

(Effects of the Invention) As explained above, according to the present invention, the contacts of the switch body are switched in the vertical direction, which is the original pressing direction, on one side of the pushbutton operation, so that malfunctions do not occur. Switch operation is possible.In addition, excessive pressing force is not applied when the switch is operated, so there is no damage to parts.Furthermore, the configuration can be greatly simplified, so the number of parts is small and it is inexpensive. It has the effect of being able to provide
