Abstract
This invention pertains to a circuit for controlling an electric device in a motor vehicle such as a light. The circuit has a control switch, a door switch and a semiconductor switch. The control switch activates the device either directly, or through the door and semiconductor switches. The control switch also has a neutral position in which the device is deactivated and the semiconductor switch is off reducing the current drain of the device on the motor vehicle battery.
