DOOR LOCK POSITION SENSOR

摘要

In a door lock having a housing and a latch plate which is pivotally connected to the housing through a pivot shaft, there is arranged a position sensor for detecting an angular position of the latch plate. The sensor comprises a rotary switch securely connected to the housing, the rotary switch having a rotating shaft which causes ON and OFF conditions of the switch upon rotation thereof; and a link mechanism operatively arranged between the rotating shaft and the pivotal latch plate so that the pivotal movement of the latch plate induces a simultaneous pivotal movement of the rotating shaft of the switch. The rotary switch is placed at a position other than a position where an axis of the pivot shaft is placed.
