Description

[Detailed description of the invention] This invention is attached to an illuminated switch.
This invention relates to the structure of a display holder that holds a light-emitting display such as an LED.

Conventional illuminated switches have been designed separately from the beginning as a push button type or a swing type, and it has not been possible to freely change the operation method by simply replacing the button. In this invention, the display body is attached to the holder in advance and then incorporated into the switch body, and a swing-type button can be attached to this holder.By simply replacing the button, it can be changed to a push-button type or swing-type button. It is an object of the present invention to provide a display holder that can provide an illuminated switch that allows the user to freely select the operating method of the mold.
An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an example of a conventionally used small push button switch 10. 11 is a substantially dome-shaped plunger made of an insulating elastic material;
The head of the plunger 11 projects above the switch case 12. A movable contact 13 made of conductive rubber or the like is fixed to the ceiling inside the dome of the plunger 11, and when the plunger 11 is pushed down, it comes into movable contact with a pair of fixed contacts 14 implanted in the case 12. The child 13 contacts to short-circuit these. 15 is case 12
A recess 16 formed on the side surface of the case 12 is a cover attached to the upper part of the case 12.

FIGS. 2 and 3 show a display holder 2 according to the present invention added to such a conventional push button switch 10.
0, a display body 30, and a swing-type illuminated switch configured by adding a swing-type button 40.
The holder 20 made of synthetic resin consists of a frame-shaped part 21 that is open at the top and bottom, and a support part 22 that is integrally provided on one side of the frame part 21. The protrusion 23 is integrally formed. Space 24 inside the frame-shaped part 21
is for accommodating the switch 10, and a hook portion 25 is formed on the inner surface of the frame-shaped portion 21 in correspondence with the recess 15 provided in the switch 10. 26
is a stepped portion provided at the rear end of the holder 20, and 31 is a terminal of the display body 30 extending downward through the support portion 22. The swing-type button 40 made of synthetic resin is
It has a pair of legs 41 protruding downward at one end and a through hole 42 through which the display body 30 passes, and the other end has a hook piece 43 that can be engaged with the step 26 of the holder 20. There is. 44 is the protrusion 2 of the holder 20
This is a small hole formed in the leg piece 41 corresponding to No. 3. The button 40 has a small hole 44 that is fitted into the projection 23 and is pivotably supported so that the button 40 can freely rotate around the projection 23.
The lower surface of the plunger 11 is in contact with the head of the plunger 11. By engaging the hook piece 43 with the stepped portion 26, the button 40 is prevented from rotating in the opposite direction and lifting up.

The illuminated switch configured in this way has button 40.
When pressed, it rotates around the protrusion 23, and its lower surface pushes down the plunger 11 to operate the switch 10.

To assemble this illuminated switch, display 3
Insert the pre-assembled switch 10 from below into the empty space 24 of the holder 20 on which the holder 0 is attached, engage the hook 25 in the recess 15, and then engage the hook 43 in the step 26. The protrusion 2 is inserted into the small hole 44.
3, the button 40 is attached to the holder 20.
Just attach it to the

In addition, in the above embodiment, the protrusion 2 is provided on the holder 20.
3 and a small hole 44 in the button 40, it is of course possible to form a recess in the holder 20 and provide a protrusion on the button 40 side that fits into the recess.

As is clear from the above explanation, the present invention provides a display holder that is attached to an illuminated switch.
a frame-shaped part that has a cavity for accommodating the switch that is open at the top and bottom, and has a part for engaging with the switch case, such as a hook part 25, on the inside;
It consists of a support part to which the display body can be attached, and is characterized in that a fitting part consisting of a protrusion or a recess capable of pivotally supporting a swing-type button is integrally formed on the side surface of this support part. be. Holder 20 according to the present invention
In addition to the swing-type illuminated switch shown in Fig. 2, the switch to which the switch is attached can be a swing-type switch without a display by not attaching the display body 30 and replacing it with a button without a through hole 42. It can also be configured to
By simply replacing the swing type button 40 with a push button type button 50, it is possible to construct a push button type illuminated switch as shown in FIG. 4.

As mentioned above, according to the present invention, by attaching a display holder to the conventional push-button switch body, it is possible to not only add a display function to the switch, but also to make it possible to use either the push-button or swing-type operation method. can also be freely selected. Therefore, a push button type switch and a swing type switch without a display, as well as an illuminated push button type switch and a swing type switch, can be easily constructed by sharing the main parts.
