US Patent 7971445 Cableless air conditioner control system and method

A cableless control system for an automobile air conditioner includes a slide pot potentiometer assembly for connection to an actuator arm on the back of a dashboard mounted control assembly. The position of the slide pot potentiometer assembly creates an electrical resistance signal which governs the position of the devices which moves the variable mechanical portions of the automobile air conditioner. The shape of the linear slide pot potentiometer assembly allows for the use of existing hardware and eliminates the need to run sheathed cables from the dashboard mounted control panel assembly to the mechanically variable portions which govern the operation of the automobile air conditioner.
