摘要： A switch includes a switching mechanism, an operating mechanism with a key which normally causes the switching mechanism to be in a switched-off condition when it is pulled out and to be displaced against a biasing force to be in a switched-on condition when the key is inserted, and a locking mechanism for maintaining the switching mechanism locked in the switched-on condition and releasing it from the locked condition if a load greater than a specified magnitude is applied to the key while the switching mechanism is locked such that the switching mechanism is set back in the switched-off condition. The switching mechanism may be contained in a head case attached to a main case containing the operating mechanism. The main case also includes a forcing mechanism which tends to force the switching mechanism in the switched-off condition. Normally when the head case is attached to the main case, the forcing mechanism is released from its forcing function but when the head case is removed from the main case, the forcing mechanism functions to displace the switching mechanism into the switched-off condition.
摘要翻译：开关包括切换机构，具有钥匙的操作机构，当钥匙被拉出时，通常使开关机构处于关闭状态，并且当所述切换机构在所述切换机构处于打开状态时，钥匙被插入，以及锁定机构，用于在切换机构被锁定时将切换机构保持在接通状态下锁定并且将其从锁定状态释放，如果大于指定幅度的负载被施加到钥匙，使得切换机制回到关闭状态。切换机构可以包含在附接到包含操作机构的主壳体的头部外壳中。主壳体还包括迫使切换机构处于关闭状态的强制机构。通常当头部外壳安装在主机壳上时，迫使机构从其强制功能中释放出来，但是当主机从主机壳拆下时，强制机构将切换机构置于关闭状态。

摘要： A door switch disclosed includes a switch body and a key unit which are attached to a structure and a door, respectively. The switch body is provided with a door key insertion hole and a switch contact. The key unit has a door key and a door key drive mechanism in its unit case. The door key drive mechanism retreats the door key into the unit case when the door is opened and protrudes it out from the unit case when the door is closed, to thereby insert the door key into the door key insertion hole in the switch body, thus turning ON the switch contact.

摘要： A lock switch apparatus comprises: a key insertion hole 7; a detection switch unit 9 for detecting the insertion of an operation key 2 in the key insertion unit 7; a lock unit 11 for locking the operation key 2 when the operation key 2 is inserted in the key insertion hole 7; and a lock detection unit 13 for detecting the operation state of the lock unit 11. The lock unit 11 is configured so that the operation key 2 is locked by the attraction of a solenoid 12, 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 12, and vibration/impact absorbing means 14 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.
