め装置。 A cylindrical key with one end open is removably fitted onto a rotor protruding from the front of the switch body, and the rotor is rotated through the key, wherein the rotor is attached to the switch body. A positioning means is provided to stop and hold the key at each ON and OFF rotational position with a constant locking force, and a constant frictional force is applied to the fitting portion between the key and the rotor to prevent the key from freely rotating. By inserting the protrusion on the outer peripheral surface of the rotor into a slit formed in the peripheral wall of the key along the axial direction, the key and the rotor can rotate together, and the peripheral wall of the key communicates with the slit, A device for preventing a key switch from being removed, characterized in that a dovetail-shaped notch is formed to prevent the key from being removed, into which the protrusion is inserted during an ON operation.
