Abstract:
An electronic central locking system (1) for motor vehicles and operating systems for locks or the like, the system comprising:a plurality of actuating elements for actuating respective ones of the locks; a controller for operating the actuating elements and supply voltage lines interconnecting the controller with respective ones of the actuating elements for powering the actuating elements; a plurality of switches connected to respective ones of the actuating elements, each switch being serially connected between its actuating element and a respective one of the supply voltage lines for applying voltage of the line to the actuating element, each of the actuating elements with its switch constituting a single unit, and each of the switches being operative in response to a code; and means within the controller for providing a code to activate each switch of the plurality of switches to conduct electric power to the switch from its respective supply voltage line; wherein, in order to drive an actuating element (23-28), the supply voltage lines (31, 310, 32) are switched by a respective one of the switches (34, 340, 37, 370) by application of a coded signal to the switch.
