Abstract
A device for controlling components of electrical equipment of a motor vehicle, such as flashing direction indicators, warning lights, side and rear lamps, etc. Respective control switches actuable by the driver of the vehicle, control circuit units for processing control signals from the control switches, control relays activated by the control circuit units to supply the components, and a synthesis circuit common to all of the control circuit units and providing a common supply output for all the control circuit units are provided. The synthesis circuit has a prepositioning circuit providing a prepositioning output, and a general clock adapted to serve as a time base for the system by controlling an input shifting circuit, in each control circuit unit, to shift a transient control signal such that it is provided at the output of the input shifting circuit when its duration is of at least one clock period. Each control circuit unit also has a memorizing circuit responsive to the prepositioning output for memorizing the control signal provided at the output of the input shifting circuit.
