摘要： PURPOSE: To enhance safety during use by providing lock arms by which locking portions are releasably locked into a locking recess and unlocking members by which time lock of the locking portions of the lock arms in the locking recess is undone. CONSTITUTION: When the insertion portion 36 of a key 10 is inserted into a key hole 13 in a key switch main body, the ends of right and left insertion-bar portions 38R, 38L abut and press the projecting parts of the horizontally operating portions 26, 27 of unlocking portions 23R, 23L outside a rotating cam 15. Then the members 23R, 23L are rotated counterclockwise, and the unlocking lever portions 28 of the members 23R, 23L rotate lock arms 24R, 24L against a spring 25. Locking portions 31 at the ends of the arms 24R, 24L are therefore unlocked from a locking recess 22 to undo a lock. On removal of the key 10 a plunger 7 is pushed down by the reverse action to insertion, a switch portion is turned off, the arms 24R, 24L are pressed by the spring 25 and turned, and the locking portions 31 are locked into the locking recess 22 to lock the cam 15.
