A key controlled lock for electrical switches, etc., in which a rotatably supported plastic switch actuator element is provided with a substantially diametrically extending keyway at one end to receive a key. Locking fingers of a plastic yieldable locking device normally engage in opposite side of the keyway. The key, upon insertion in the keyway, cams the fingers outwardly to release the actuator element for rotation by the key.
