Control equipment for vehicle starter motor, comprises control circuit, semiconductor relay to control electromagnetic switch and means to detect control signal using voltage on semiconductor relay

摘要

The starter key is connected directly to the coil (6) of a electromagnetic switch (5) which operates the main contactor (2). The electromagnetic switch coil is energized through a semiconductor relay (12) and the relay voltage is used to determine whether the starter key is presenting a control signal or not and whether the control circuit (11) is energized and the relay operative or not
