ABSTRACT:
An apparatus for temporarily shutting off electric power to an air conditioning compressor of a vehicle is provided. The apparatus comprises a fixture having bent and upwardly extending sides that form a seat adapted to receive a portion of a tube. A piston is slidably received in the tube and has a rod securely attached to one end thereof. A linking rod is secured to the opposite side of the piston, and a spring plate of a microswitch is connected to the linking rod for turning the microswitch on and off. When the microswitch is turned off, an air conditioning compressor is no longer supplied with electric power. A central processing unit is connected to the microswitch and has a counter to count the shut off time of the electric power supplied to a compressor, and to resume the supply of electric power to the air conditioning compressor when a preset time has elapsed.
