The fixed contact 14 faces each other, the contact 8 fixed to the contact piece 9 of the terminal part 11 and the contact 12 fixed to the contact piece 13 of the terminal part 17 face each other, and a movable contact is placed between the contacts 6 and 14. 5
1, and between the contacts 12 and 8, movable contacts 45 are swingably supported on the support ridges 32 of the terminal section 35 and the support ridges 28 of the terminal section 31, respectively, and are opened by the operation of the operation button 58. The contacts are switched via the swing spring 59 and the swing spring 57.

One lead wire 68 of the display lamp 63 disposed in the display window 61 provided in the operation button 58 is directly connected to the swing spring 57, and the other lead wire 64 of the display lamp 63 is connected directly to the printed wiring board 62. One lead wire 6 of the resistor 65 is connected through the printed wiring 67 of
6, and the other lead wire 6 of this resistor 65
9 is connected to the swing spring 56, the indicator lamp 63 is off when the lighting fixture 70 is on, as shown in FIGS. 5 and 6, and when the lighting fixture 70 is off, Display lamp 6
Since I wired it so that light fixture 3 lights up, for example, light fixture 7
Even when 0 is off, the location of the switch can be clearly known by lighting the indicator lamp 63.

As described above, according to the present invention, the printed wiring board 62 and each spring 57 and 59 are connected to the operation button 5.
The indicator lamp 63 and the resistor 6
5, the lighting circuit consisting of the lighting circuit 70 can be connected extremely easily, and its assembly configuration is extremely easy.Furthermore, due to the existence of the lighting circuit described above, one lighting fixture 70 can be installed in many locations. When operating the switch, the flashing state of the load can be detected from a distance, and when the load is off, the indicator lamp 63 lights up, making it possible to clearly recognize the switch position even in the dark. It has the following effects.
