Abstract

A lock switch apparatus comprises: a key insertion hole ; a detection switch unit for detecting the insertion of an operation key in the key insertion unit ; a lock unit for locking the operation key when the operation key is inserted in the key insertion hole ; and a lock detection unit for detecting the operation state of the lock unit . The lock unit is configured so that the operation key is locked by the attraction of a solenoid , a movable system of a solenoid-side movable portion is configured by providing an associatively movable portion which moves in association with the solenoid-side movable portion with respect to the solenoid-side movable portion of the solenoid , and vibration/impact absorbing means is provided to provide a balance state of operating forces applied to the movable system. Thereby, there can be provided a lock switch capable of preventing a malfunction of switch signal due to an inertia force of the solenoid-side movable portion of the solenoid and capable of being made small in size.
