Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improved small-sized illuminated switch, and in particular, a movable handle equipped with an illumination light emitter is actuated to activate the main contact and the illumination. In a toggle switch, waveform switch, slide switch, etc. that opens and closes a circuit, when operating a converter for opening and closing the main contact provided at the end of the movable handle, select the connection direction to the terminal for the light emitter circuit. For this reason, the above-mentioned lighting circuit is turned on and off.
A single switch can have any combination of illumination circuit connections, such as off (flashing) and always on (illuminated) states, or on/off and two-color lighting. This invention relates to a small illuminated switch that can be used as a light switch.

[Conventional technology]

A conventional light-emitting small switch has a structure in which the opening and closing of the switch circuit and the opening and closing of the illumination circuit are linked, for example, by operating a movable handle.

[The problem that the idea aims to solve]

However, in such conventional devices, the illumination is turned on and off as the movable handle is operated, and is always on regardless of the handle operation.In other words, it is a switch that is placed in a dark place, for example, and when the switch is turned off, the illumination is turned on and off. However, it had the disadvantage that it could not be used as a switch to maintain a constantly illuminated state, such as to clearly indicate its position by illuminating it.

The purpose of the present invention is to provide an illuminated small switch that overcomes the above-mentioned drawbacks, and when operating the converter for opening and closing the main contact provided at the end of the movable handle, the illumination circuit is turned on and off. A lighted small switch that can be turned on or always on by selecting the connection to the fixed terminal for the light emitter circuit, and allows any combination of various lighting circuit connections to be obtained in a single switch. Our goal is to provide the following.

That is, one end of the conductive coil spring 8 is press-fitted to the recess 5e formed in the central raised part 5A of the converter 5, and the other end is attached to the light emitter circuit receiving piece 2.
By being hooked to a convex portion 20a formed on the top of the light emitting body, the receiving piece 20 and the lead wire 7A of the light emitting body can be connected at all times. In this case, the upward reaction force of the conductive coil spring 8, together with the coil spring 15 of the slider 14, moves the rolling pin portion 4a of the handle 4 via the converter 5 to the rolling pin receiving portion 3c on the inner wall surface of the sleeve 3. This ensures smooth operation of the movable handle 4.

Incidentally, a conduction plate 21 having a U-shaped cross section may be interposed as shown in Fig. 7b at the connection portion between the lead wire 7A and the conductive coil spring 8, and in this case, the electrical contact can be made more accurately. It can be done.

A hole is drilled for insertion and binding. As shown in FIG. 6a, the movable contact piece 9 is inserted into the converter 5 from below through the through hole 5.
c along with the exposed portion 7b of the lead wire 7B. Since the tongue piece 9d has sufficient elasticity, it is compressed when the lower part of the through hole 5c is narrow at the beginning of insertion, but when the lower end of the tongue piece 9d rises to the step part 5d at the end of insertion, this tongue piece 9
d expands as shown in the figure, and its tongue end comes into contact with the stepped portion 5d, thereby preventing the contact piece 9 from escaping downward, and the contact piece 9 is exposed to the exposed portion 7b of the lead wire 7B. It is conveniently attached to the converter 5 together with the converter.
After mounting, the contact piece portion 9a contacts the flat portion 5f of the converter 5. The operation required for mounting and connecting the lead wire 7B as described above is extremely simple, just by simply inserting it.

Note that the through hole 5c may be modified if the contact piece 9 is inserted into the hole 5c from below the converter 5.
The upper part of the recess may be closed as shown in FIG. 6b, or it may be a recess that opens only on the lower surface. On the other hand, it is also possible to attach the contact piece 9 from the top surface of the converter 5 as shown in FIG. .

Horizontal piece 17 of contact piece 17
b, the rectangular hole 17c is also the same as above, and the terminal 18
B penetrates the bottom wall of the housing 1 and is fixed thereto. In this embodiment, the contact plate 16,
17 is the width W of the contact piece 9 as shown in the third diagram.
It is selected to be smaller. As a result, the contact piece 9 is always in contact with at least one of the contact plates 16 and 17 even during the process of operating the handle 4.

Thus, when the handle 4 is in the first illustrated position, the contact piece 9a of the movable contact piece 9 comes into sliding contact with the vertical piece 16a of the contact plate 16, and is electrically connected to the contact plate 16. When the handle 4 is tilted to the opposite side, the contact piece 9a of the contact piece 9 comes into sliding contact with the vertical piece 17a of the contact plate 17, so that the contact plate 17 is electrically connected. Therefore,
By short-circuiting the pair of light emitter circuit fixed terminals 18A and 18B and connecting one side of the electric wire from the power source to the light emitter circuit receiving piece 20, the light emitter 6 for constant illumination can be raised and lowered. The state obtained is as follows. In addition, fixed terminal 18A for light emitter circuit,

It corresponds to 9B and has a sliding contact structure. Therefore, according to this embodiment, the contact piece 29A is brought into contact with the left contact plate 36 to illuminate the light emitter in red, for example, and then the handle 24 is tilted to the opposite side, and the contact piece 29A is brought into contact with the left contact plate .
9B can be brought into contact with the right contact plate 37 to change the illumination to, for example, green, thus providing two-color light emission. That is, regardless of whether the main contact is on or off, the light always emits light, although the color changes.
Also, in this embodiment, if a power source is not connected to either one of the contact plates 36, 37, it is of course possible to use monochrome flashing illumination.
