ABSTRACT:
A composite switch for starting and stopping the air conditioner of a vehicle and for changing the flow of air supplied by an air blower comprises a main switch, a selector switch, and an auxiliary switch that is connected in series with the main switch. The main switch is used to start and stop the air conditioner. The selector switch is used to change the flow of air. A selector member for switching the contacts of the auxiliary switch from one state to another is disposed opposite to an actuating member for shifting the contacts of the selector switch such that whenever the selector switch is in a certain position, the actuating member drives the selector member to open the main switch. Thus, whenever the blower is stopped, the air conditioner is stopped.
