ABSTRACT:
A breakaway device (10) to detect when a towed vehicle (14) separates from a towing vehicle (16) in order to engage the towed vehicle's brakes broadly comprises a sensor operable to detect when a signal from the towing vehicle (16) is lost and a shunt operable to route electrical power to the brakes. In a preferred embodiment, the sensor and the shut may be embodied in a transistor (26). In an alternative embodiment, the sensor and the shut may be embodied in an electro-mechanical switch (34). The device (10) preferably includes an override (42) and lights (44,46) to indicate the device's (10) status.
