Electric Fan Switch Diagram. The temperature controlled switch is designed to turn the fan on when coolant temperatures reach 195 degrees and turn off the fan when temps drop to 185 degrees. Suggested electric fan wiring diagrams converting a 12 volt switch into a ground switch these diagrams show the use of relays on off sensors on off switches and on off fan controllers.
It reveals the elements of the circuit as streamlined forms and the power as well as signal links between the tools. This wiring method is used when the power source is from the switch and one wants to control the fan and light from that single switch. The hot source is connected directly to the bottom terminal on the switch.
