摘要

The device (20) has electrical connectors (58, 60, 62, 64), which are controlled by a switch, where the device has a control device (22) for the switch. The switch is controlled depending on a control signal from a towing vehicle (10) and is designed as a three-condition switch. The electrical connectors with the switch are selectively connected with positive and negative terminals (32, 30), where the switch includes two power transistors.
