る効果がある。(2)...Thus, by providing a rotor rotatably and vertically movably below the tip of the movable contact spring piece installed in the charged state, the plate-shaped body is inserted into the recess of the switch of the present invention. When the rotor rotates, the plate-shaped body is smoothly received, and at the same time, it moves upward in the vertical groove and bends the movable contact spring piece upward to reliably separate both contacts.
Therefore, there is an advantage that the rotor can perform the insertion detection function of the plate-like body and the opening/closing function of the switch extremely smoothly and accurately.
