Five wire rotary blower fan switch. The rotary blower switch is the most common switch on aftermarket a A/C systems with rotary controls. The switch is also used on some round or oval billet control panels. This is a three speed, four position blower switch. The switch is designed to run the blower motor at low, medium, and high speeds, as well as turn the compressor on (through the thermostat).
This switch is good up to 20 amps. Our 12 volt blower motors do not draw more then 16.8 amps.
