Description

[Detailed Description of the Invention] The present invention relates to a push button switch that can be formed by simply inserting a contact having one pole in common from the side of the switch body, has a simple structure, and is reliable in operation.

Conventional push-button switches have a complicated structure and are time-consuming to assemble, and also have drawbacks such as malfunctions due to abrasion of various parts during long-term use.

In view of this, the present invention involves molding the push button and the switch body from synthetic resin, and inserting the contact from the side of the switch body, which allows accurate and simple assembly.
This is what was done.

The present invention will be explained below based on examples.

In the figure, 1 is the switch body molded from synthetic resin.
Two push buttons 2 are provided on the top surface of the switch body 1 in the longitudinal direction.
, 2 is provided in the vertical direction, and a spring S for returning the push button is provided on the bottom surface of both ends of the long groove 11.
1, a recess 12 for fitting the end of S1,
There will be 11.

Also, on both sides of both ends of the long groove 11 of the switch body, there are contact insertion holes 13, 13'k for allowing the two contacts 3, 3 to be inserted horizontally in parallel, and are perpendicular to the long groove.

Set it as c5. The lower piece 17 of each contact insertion hole 13
A screw hole 19 is provided at the center of the lower piece on the lower side, that is, on the outside, for providing five contact pieces, and four common contact pieces are machined on the side of the switch body on both sides of the switch body 1. It is formed into an insertion groove 15 for insertion.

This insertion groove 15 is formed between the upper protruding piece 20 and the lower protruding piece 21, and a mounting piece 22 having all the mounting holes for fixing the switch body is provided approximately in the middle of the insertion grooves 15, 15 on both sides. It is a conflict that forms.

The push button 2 is integrally formed with a rectangular guide part 2b' having a circular shape at the top and a long hole 2ak at the bottom.
A protrusion 2ck is provided on one side of b to protrude horizontally.

The contact 3 has silver contacts 3at3a on both ends of one side thereof.
The contact piece 5 is made of a rectangular conductive metal plate with a conductive metal plate bent in a U-shape, and is attached to the bottom of the lower piece 17 provided on the switch body 1 on the side that does not have the cut groove. One piece of this contact piece 5 is provided with a silver contact 5ak, the other piece is provided with a screw 5bk for connecting the lead wire etc., and the common contact piece 4 is fixed by being tightly fitted into the groove 18 of the piece 17.
Similar to the contact 3, a strip-shaped conductive metal plate is used to extend the length of the switch body 1+, and a silver contact is placed opposite the contact 3, which is inserted into the contact insertion hole of the switch body. 4a t 4a'k, also main body 1. Both ends of the common contact piece protruding to the outside (F-engaging hole 4b and screw hole 4
c.

To assemble each member constructed as described above, first insert the spring 5 into the recesses 12, 12 in the long groove of the switch body.
11s1', the projections 2c, 2 are inserted into the long groove 11.
Fit the push buttons 2.2 so that the buttons c face each other.

At this time, a semicircular lever 6 is interposed in the long groove between the rain push buttons, and the lever 6 has a shaft 6a on both sides of the center.
When the L/Gover f is inserted into the center of the long groove, the shaft 6at6a fits into the shaft support groove provided on the inner surface of the long groove, and the shaft 6ak functions as a fulcrum and can freely swing like a seesaw. Also, both ends of this lever are brought into contact with the lower surfaces of the protrusions of both push buttons.

Next, while pressing the push buttons 2, 2 by compressing the spring 81, insert the contacts 3, 3 into each push button elongated hole with the silver contacts facing downward, and furthermore, the push button guide portion A spring 82 is inserted into the elongated hole, that is, between the upper inner surface of the elongated hole and the upper surface of the contact, and the elasticity of both springs causes the contact to be in the neutral position, that is, the contact insertion hole of the switch body, unless external force is applied to the push button. Align it so that it is on the top edge.

Then, by inserting the common contact piece 4 into the cut groove from the side of the switch body into the insertion groove formed by the upper piece and the lower protruding piece, the desired push button switch is constructed. be.

When two or more push button switches are used in a row at the bottom, one end of each common contact piece may be engaged with the attached screw.

According to the present invention, the push button insertion hole and the mounting parts of each contact are formed integrally with the switch body, and the common contact piece is fixed by being inserted upward from the side of the switch body, making it easy to assemble. It has advantages such as no failure and reliable operation.
