Description

[Detailed Description of the Invention] The present invention relates to an illuminated pushbutton switch, and more particularly to an illuminated pushbutton switch in which an illumination part is detachably attached to a switch case.

This type of illuminated pushbutton switch with a removable illumination section requires an elastic locking piece to be removably attached to the case.

In conventional devices, this elastic locking piece was integrally molded with a holder made of a synthetic resin material for holding the light emitter.

The present invention aims to improve durability by constructing this locking piece with a metal member, and also integrates the contact piece that forms the connection part of one electrode of the light emitting body with the locking piece, thereby reducing the number of parts. An object of the present invention is to provide an illuminated pushbutton switch with reduced irradiation.

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, a synthetic resin color cap 1 protects the push button and functions as a window for guiding light from a light emitter 5 to the outside.

This color cap 1 is attached to an operating shaft 2 made of synthetic resin.

The operating shaft 2 has legs 21 and 22.

The holder 3 has a mounting hole 31 for a light emitter 5 such as a lamp or LED.
It is molded from synthetic resin so as to have a groove 32 for mounting the fixture 4.

The fixture 4 includes a bottom surface portion 41, a hole 42 for penetrating the light emitting body 5 provided approximately at the center of the bottom surface portion 41, locking pieces 43 and 44 extending elastically upward, and the above-mentioned. It has a tongue piece 45 that elastically extends above the hole 42 and a contact piece 46 that extends upward from near the outer edge of the bottom part 41 and is bent into an L-shape.

This fixture 4 is formed by punching out an elastic metal plate and then bending it.

In this fixture 4, the contact piece 46 is inserted into the groove 32 of the holder 3, the tongue piece 45 is inserted into the mounting hole 31 of the holder 3, and the tongue piece 45 and the contact piece 46 It is attached to the holder 3 with the part in between sandwiched therebetween.

The state in which the fixture 4 is attached to the holder 3 is as shown in FIG.

After integrating the holder 3 and the fixture 4 in this way,
When the light emitter 5 is inserted into the hole 42 and the mounting hole 31 from the bottom to the top, the electrode 51 provided on the outer peripheral surface of the light emitter 5 comes into contact with the tongue piece 45, and the tongue piece 45 is inserted into the mounting hole. 31 and the inner wall surface and press it.

As a result, the light emitter 5 is installed in the mounting hole 31 of the holder 3, and the holder 3, the fixture 4, and the light emitter 5 are firmly integrated.

The thus integrated unit is attached between the legs 21 and 22 of the operating shaft 2, and then inserted into the front opening 61 of the case 6.

Then, the locking pieces 43 and 44 elastically engage with the locking part 62 provided on the inner surface of the opening 61 of the case 6, and the holder 3
, the case 6 is the one in which the fixture 4 and the light emitting body 5 are integrated.
held fixedly within.

In this state, the operating shaft 2 and the collar cap 1 are held slidably, and the collar cap 1 is urged by a spring or the like (not shown) in a direction to protrude from the case 6.

Also, at this time, the outer surface of the contact piece 46 is connected to the opening 61 of the case 6.
It comes into contact with a connection terminal (not shown) provided near the inner surface of the.

Furthermore, the other electrode provided on the bottom surface of the light emitter 5 is also connected to the case 6.
contacts a connection terminal (not shown) provided near the bottom of the opening 61.

In this way, it becomes possible to supply lighting current to the light emitter 5.

When the operating shaft 2 and the illumination unit including the light emitter 5 are attached to the case 6 in this way, when the front end of the color cap 1 is pressed, the tips of the legs 21 and 22 are installed near the bottom of the case 6. A switching operation is performed by pressing a switch mechanism (not shown).

When the switching operation is performed, a current is supplied to the light emitter 5 and the light emitter 5 lights up.

The light is then emitted from the color cap 1 to the outside to indicate that a switching operation has been performed.

When the collar cap 1 is pulled out together with the operating shaft 2 from the opening 61 of the case 6, the holder 3 and the like held between the legs 21 and 22 are also pulled out.

This is because the illumination part of the holder 3 etc. is held by elastic engagement between the locking pieces 43, 44 and the locking part 62, and this engagement is released when force is applied in the drawing direction. .

In this way, the illuminating section is taken out from the case 6 and replacement work is performed when the illuminant 5 breaks down or the like.

As described above in the embodiments, according to the present invention,
The fixture 4 is made of elastic metal and has locking pieces 43, 4.
4 is integrally formed, and a tongue piece 45 that contacts the electrode 51 of the light emitting body 5 and a contact piece 46 that contacts a connecting terminal provided near the inner surface of the case are also formed integrally.

Therefore, since the locking pieces 43 and 44 are made of metal, durability is improved, and since the fitting 4 forms a connection part for one electrode of the light emitting body 5, the number of parts is reduced and assembly is facilitated. This gives you the advantage of being able to do so.
