Vehicle door locking system.

摘要

Actuator for vehicle door lock, particularly for use in electrically powered central locking systems, has a plunger or other actuator member (16) which is shifted between first and second positions on locking and unlocking the related door latch. Said member carries an electrical contact element (24) which coacts with one or more fixed contacts (34,36,38) in the walls of a housing or other guide formation (12) to close one or more respective circuits at said position or positions for operating other parts of the related system and/or signalling the condition of the related lock e.g. whether it is locked or unlocked. Preferably the contacts slide into and out of engagement to provide silent operation and self-cleaning wiping action.
