Description

[Detailed Description of the Invention] The present invention relates to an illuminated push button switch, and more specifically to an illuminated push button switch that opens and closes the switch means as appropriate and lights up a lamp by the movement of a push button slidably mounted inside the main body case. It is something.

Conventionally, in this type of illuminated push button switch, as shown in FIG. The terminal 23 is installed in the center (see Figure 1 A and C), and the switch terminal 23 is installed on both sides and the lamp terminal 19 is installed in the center (see Figure 1 B). was provided.

However, in these cases, the lamp terminal 1
9. Since each group of switch terminals 23 is installed to sandwich the other group, and the lamp terminals 19 and switch terminals 23 are connected to different power sources, the lead wires of the power sources may cross and get twisted. This may lead to poor contact of the lead wires, or it may be difficult to determine whether the installed terminal is the lamp terminal 19 or the switch terminal 23, leading to the risk of wiring errors.

This invention was made in view of the above drawbacks,
The main purpose is to provide an illuminated push button switch in which a lamp terminal group and a switch terminal group are arranged as separate groups, thereby eliminating the risk of wiring errors and the crossing of lead wires.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings, which are examples of the present invention.

The illuminated pushbutton switch according to the present invention is comprised of an illumination section 4, a lamp terminal unit 14, and a switch terminal unit 21 housed in a cylindrical main body case 1 having a generally rectangular cross section. The illumination unit 4 consists of an operating member 8 equipped with a transparent cap 5, a dial 6, and a color plate 7, and a lamp stand 11 on which four lamps 12 are arranged side by side. The lamp stand 11 is held between a pair of operating legs 9, which have claws 10 protruding from both sides. The illumination part 4 is inserted into the main body case 1 from above, the lamp base 11 is fixed by a locking part (not shown) of the main body case 1, the operating member 8 is slidable up and down, and is prevented from coming off upward. This is done by the claw portion 10 engaging with the lower edge of the lamp stand 11.

As shown in FIG. 5, the lamp terminal unit 14 has a lamp terminal 1 mounted on a substantially rectangular parallelepiped resin insulating stand 15.
9. Common lamp terminals 20 are installed side by side. The switch terminal unit 21 is constructed by integrally assembling two small micro-switches 22 arranged side by side and sandwiched between approximately rectangular parallelepiped resin insulating stands 24a, 24b with separators 27, 27 interposed between them. 23 projects downward from the switch 22. In addition, an operation lever 28 and a sub-lever 29 having a protrusion 30 formed on one side thereof, which constitute a well-known reversing mechanism, are each rotatably mounted, and a quick spring 31 is tensioned to the operation lever 28. Provides reversibility.

Each of the above units 14, 21 is fitted with the protrusion 16 of the insulating stand 15 opposed to the recess 25 of the insulating stand 24a, and the recess 17 of the insulating stand 15, 24b,
26 is fitted into the protrusions 3, 3 of the main body case 1 to be housed in the lower part of the main body case 1. At this time, the protrusion 30 of the sub-lever 29 is inserted into the recess 15 formed in the insulating base 15 of the lamp terminal unit 14.
The operating legs 9, 9 of the operating member 8 can come into contact with the main body A and the protrusion 30 of the sub-lever 29. Further, the tip 19a of the lamp terminal 19 contacts the protruding contact portion 12a of the lamp 12, and the tip 20a of the common lamp terminal 20 contacts the lamp contact piece 13 connected to the annular contact portion 12b of the lamp 12. There is.

This illuminated push button switch has a mounting bracket 32 fixed to the side of the main body case 1, is inserted into a mounting hole in a panel (not shown), and the edge of the mounting hole is connected to the flange portion 2 and the curved arm of the mounting bracket 32. 33, 33 are clamped and fixed. Also, lamp terminal 1
Lead wires (not shown) are connected to the switch terminals 9, 20 and 23, respectively.

The operation of the illuminated pushbutton switch is similar to its conventional counterpart. That is, in the normal state, the sub-lever 29 is urged upward by the quick spring 31, and the portion A and the protruding portion 30 shown in FIG. . A push button (not shown) of the microswitch 22 is pressed by an operation lever 28.

Now, if you push down the cap 5, the operating member 8
moves downward, and the sub-lever 29 is pressed by the operating legs 9 and rotates downward, and the operating lever 28 is reversed upward, and the micro switch 2
The pressing force on the push button 2 is released, the micro switch 22 is operated, and the lamp 12 is turned on.

According to the present invention, the lamp terminal unit is made into a unit by mounting all the lamp terminals side by side on one substantially rectangular insulating stand, and the switch terminal unit is formed by sandwiching a micro switch having switch terminals between the insulating stand having a substantially rectangular parallelepiped shape. Since the two units are connected facing each other and fitted into the case, the lamp terminal group and the switch terminal group become independent and separate groups, and the lamp terminal group and the switch terminal group become independent groups. When connecting lead wires to the terminal group and the switch terminal group, it is possible to easily identify which terminal group the terminal group belongs to. Further, even when a power source is connected to the lamp terminal and the switch terminal, the lead wires do not cross or twist, and poor contact does not occur, making wiring easy.
