Switching device with electrical switching configuration for use in motor vehicle, has relay coils connecting to power supply unit, which provides actuating voltage for relays and controls each relay individually

摘要

The switching device has relay coils connecting to a power supply unit (3), common for all relays. The power supply unit is attached to a control unit (5), which supplies a control signal. The power supply unit provides an actuating voltage or a withstand voltage for the relays, and is connected with respective relays, so that each relay is controlled individually.
