Abstract
The central locking system for motor vehicles comprises a plurality of catch drives reversibly driving between a locking position and an unlocking position. The catch drives are switched on for a pre-determined time duration in the locking direction by drive signals of a first time control circuit. The catch drives are energized in the unlocking direction by a second time control circuit for a pre-determined time duration. The time control circuits can be triggered alternately through a triggering control switch actuatable by means of a door key from outside the vehicle, or by means of a press-button switch actuatable from within the motor vehicle. The trigger inputs of the time control circuits are connected through separate trigger paths to the press-button switch.
