Description

[Detailed explanation of the invention] This invention relates to the structure of a push/pull switch, and its purpose is to have a small number of parts,
The purpose is to provide a product that is easy to assemble and works at a low price.

Conventional push/pull switches often have built-in reversing springs, etc., have a large number of parts, and are time-consuming to assemble.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a frame formed by punching and bending a metal plate, and the frame 1 is provided with protrusions 1a, 1a for mounting a board. 2 is a sliding body molded from synthetic resin;
The sliding body 2 includes an operating portion 2a, a stopper portion 2b,
2b and a convex cam ridge 2c on the upper surface. Reference numeral 3 denotes a leaf spring made of an elastic metal plate, and the leaf spring 3 is formed with a roughly square-shaped spring piece 3a.
The spring piece 3a is provided with a U-shaped protrusion 3b.
4 is a coil spring that always biases the sliding body 2 in one direction; 5 is a movable contact piece made of conductive elastic metal;
The movable contact piece 5 is stored in a storage portion 2d provided in the abdomen of the sliding body 2. 6 is fixed terminal 7a, 7
This is an insulating substrate on which parts b and 7c are implanted.

Next, to explain the operation of the push-pull switch of the present invention, in the state shown in FIG. The elastic force of the spring piece 3a is greater than the return force of the convex cam ridge 2c.
is held in contact with the U-shaped protrusion 3b, and the movable contact piece 5 is located on the fixed terminal 7b. When the operating part 2a is pressed in the direction of arrow A from this state, the sliding body 2 and the movable contact piece 5 move as shown in FIG. . When the pressing is stopped, the sliding body 2 and the movable contact piece 5 move due to the restoring force of the coil spring 4, returning to the state shown in FIG. 3A. Next, when the operating part 2a is pulled in the direction of arrow B from the state shown in FIG. 3A,
The convex cam ridge 2c of the sliding body 2 pushes the spring piece 3a upward, and the engagement between the convex cam ridge 2c and the U-shaped protrusion 3b is disengaged, and the sliding body 2 moves, and the stopper part 2
b and 2b come into contact with the inner wall of the frame 1 and stop moving (see Fig. 3, c). At this time, the movable contact piece 5 also moves to establish electrical continuity between the fixed terminals 7a and 7b. When the operating portion 2a is pressed from the state shown in FIG. 3C and moved until the convex cam ridge 2c passes the U-shaped protrusion 3b, and the pressure is stopped, the state returns to the state shown in FIG. 3A. Moving from Figure 3 A to Figure 3 C and 3
When moving from Figure C to Figure 3 A, convex cam mountain 2c
In order for the U-shaped protrusion 3b to overcome this, the switching is controlled.

Next, to briefly explain the assembly of the push/pull switch of the present invention, first, the leaf spring 3 is placed inside the frame 1.
Then, with the coil spring 4 attached to the sliding body 2, a part of the sliding body 2 is inserted into the frame 1, and then the movable contact piece 5 is stored in the storage part 2d of the sliding body 2, Then, the insulating substrate 6 is assembled into the frame 1 and attached by screws or the like, and the assembly is completed.

As mentioned above, the push/pull switch of this invention has a protrusion on the leaf spring and a convex cam ridge on the sliding body, so it has a simple structure, has a small number of parts, and is easy to assemble, making it inexpensive. It has practical effects such as:
