form. The inner surface of the lower part of the shaft hole 15 has a horizontal plane 17 whose center part is lowered with respect to the horizontal planes on both sides of the upper part.
The mounting concave surface 16 of the contact support plate 25, which has been
It is formed as shown in FIG. 3, and an engaging portion 18 recessed upward is provided in a part of the horizontal surface 17. The concave surface 16 continues to the lower end of the inner surface of the switch case, and an insulating plate 20 is tightly fitted into the opening at the lower end, and a locking blade 21 protruding from the side surface of the plate 20 is snapped into the opening. The stop portion 19 is provided in the shape of a horizontal hole.

As shown in FIGS. 6 to 9, the contact support plate 25 is attached by fitting approximately half of its thickness into the mounting concave surface 16 of the switch case 14, and has a horizontal engagement surface that coincides with the horizontal surface 17 on the top. 26, a horizontal joint surface 27 in contact with the upper surface of the insulating plate 20 is formed at the lower part, a protrusion 28 is formed on the horizontal engagement surface 26 to fit into the above-mentioned engagement part 18 from below, and the horizontal joint surface 27 has a Several projecting pieces 29 that engage with the insulating plate 20 are protruded. This contact support plate 25 has one to several concave surfaces 30 formed on the vertical surface as shown in FIGS. A latching hole 31 is formed at the upper end of each concave surface 30, and the lower part of the back surface of the hole 31 is carved. The fixed contact 32 is the conductive part 3
A terminal plate 34 is formed by bending the lower end of the terminal plate 34 at right angles to touch the insulating plate 20 and protruding further downward.
A bending plate 35 is provided which is bent twice and attached as shown in the figure.

The insulating plate 20 is provided with a hole as a fitting part 22 into which the protruding piece 29 of the contact support plate 25 is fitted, and the terminal plate 3
An insertion hole 23 is provided through which 4 is tightly passed through to the lower surface. Further, on the insulating plate 20, a moderation plate 36 shown in FIGS. 6 to 9 is loosely fitted from below into the moderation plate engagement groove 9 in the lower surface protrusion 5 of the lower part of the switch operation piece 1 to correspond to the ejected ball 11. The lower surface of the moderation plate 36 is in contact with the lower surface thereof, and a pair of elastic engagement legs 37 protrudes from the lower surface of the moderation plate 36, and the elastic engagement legs 37 are press-fitted into the insulating plate 20 and engaged through engagement holes. 24 will be provided.
(See Figures 11 and 12) The movable contact 38 is attached to both sides or one side of the movable contact support member 5, and has a triangularly arranged contact protruding from it, and legs 39 at both ends into which the fitting groove 7 is fitted. Contact pressure spring 4 provided and fitted into the fitting hole 8
Elastic contact with 0.

In addition, a small window hole 42 is provided in the pressing part 2 of the switch operation piece 1, and a translucent display plate 43 is provided on the upper surface of the window hole 42.
Paste.

In the present invention, the above-mentioned switch operating piece 1, switch case 14, and insulating plate 20 are configured as common members of the switch. However, the insulating plate 20 is the terminal plate 3.
There is a change in the number of insertion holes 23 through which 4 is inserted,
Since a small illumination lamp may or may not be attached, it can be manufactured separately depending on the type of switch. However, even in such a case, it is common that the locking wing pieces 21, the fitting portions 22, and the engaging holes 24 are provided at predetermined positions.

Even though the switches using the seesaw type switch operation piece 1 are the same in appearance, as shown in Fig. 6, the switch is swung approximately 15 degrees in one direction from the off position ( ) to the on position ( ), and then the same It has a switch function that rotates approximately 10 degrees in the direction to automatically return to the ON position (), and from the OFF position () to approximately 10 degrees in the other direction to automatically return to ON position (). Alternatively, as shown in Fig. 7, rotate about 10 degrees in one direction from the off position (') to the automatic return on position ('), and then rotate about 10 degrees in the other direction from the off position (').
It has a switch function that turns it to the on position ('). As shown in Figure 8, it has a switch function that swings approximately 15 degrees from the off position ('') to automatically return to the on position (''), and as shown in Figure 9, it swings approximately 15 degrees from the off position (''). to the on position (
) It is necessary to manufacture various kinds of devices, such as those having a switch function, and it is necessary to correspond to the shape of the moderation plate 36 shown in FIGS. 6 to 9.
In each case, in order to prevent excessive rocking of the switch operation piece 1, the positions of the stoppers 41 and 41 provided on the contact support plate 25 (with which the lower surfaces of the pressing parts 2 and 3 touch) and the arrangement of the fixed contacts may be changed. must be manufactured.

In the present invention, for the contact support plate 25, the horizontal engagement surface 26, horizontal joint surface 27, protrusion 28, and protrusion piece 29 are made common, while the concave surface 30 and latching hole 31 are manufactured and bent to match the required switch. Board 3
The fixed contact 32 provided with 5 is manufactured by making only the terminal plate 34 common in accordance with the contact support plate 25, and the shape of the peaks and valleys of the moderation plate 36 is also adjusted to the swing angle and automatic return function. It can be produced by making only the elastic engagement legs 37 common, and by assembling it with the basic common members mentioned above.

Figures 10 to 12 show parts such as the contact support plate 25, fixed contact 32, and moderation plate 26, which were manufactured according to the switch function shown in Figure 6, to the basic common parts of the switch shown in Figures 1 to 5. This is an example of an assembled form. In FIGS. 11 and 12, each vertex of the movable contact 38 shown as a triangle represents the position of a triangularly arranged contact point.

The present invention has the configuration shown in the above embodiment, and the switch can be assembled by providing several types of basic common parts that have almost the same external structure, such as the seesaw type switch operation piece, but have different switch functions. There are excellent benefits to be gained.
