Claims

[Scope of utility model registration request]

The movable contact body is swingably supported by a conductive metal fitting placed at the bottom of the switch body, and the upper half of the coil spring is inserted into a hole in the bottom opening made in the center rib on the bottom of the operation handle, and the coil The lower half of the spring is fitted into the movable contact body, and the coil spring is bent and reversed in response to the reversal action of the operating handle, and the movable contact body is rotated to the left and right around the support point to become the movable contact body. In a switch that brings a movable contact into contact with and opens a fixed contact on a fixed terminal board provided inside the device, a neon light is placed on the top surface of a wiring board such as a printed circuit board or a molded board with a metal lead board inside. Attach a display element such as a pipe, etc., insert the center rib from above into a hole drilled in the wiring board, attach the wiring board to the bottom surface of the operating handle, connect one end of the display element, and connect the other end to the A current-limiting resistor connected to the coil spring is installed inside the hole of the central rib so as to be pressed by the upper end of the coil spring, and is connected to the other end of the display element and comes into contact with the fixed terminal plate when the operating handle is turned to the off side. A switch operation display circuit block having a contact portion provided on the lower surface of the wiring board.
