Control circuit for central supply for car electrics - has logic switch to allow independent operation of hazard flashers

摘要

The central control circuit for the vehicle electrics has an electronic logic (1) which couples the selected circuit to the supply. A main function switch and a hazard warning switch (4) are fitted, with the hazard flasher directly coupled to the battery when in operation. The direct coupling of the hazard function prevents large current pulses passing over the main function switch and wearing the contacts. Each separate circuit is connected to the supply via a coded signal.
