These diagrams show the use of relays on off sensors on off switches and on off fan.

Electric fan toggle switch diagram.

Circuit electrical wiring enters the switch box. So now that you have a basic concept of wiring a 2 way switch let s look at the following 2 way switch diagrams to see which type of circuit scenario you have. Turns on fan when temp switch is activated 5 amp fuse signal circuit 12v switched ignition or fuse panel power on when key is in the run position. And off at 165 f.

Explanation of wiring diagram 1. And off at 175 f. Basic 2 way circuit power coming in at switch. 86 87 30 85 optional override switch turns on fan by passing temp sensor and a c relay.

At times your cooling fan stops working because a sensor has gone bad but the fan works just fine. A way to get around this situation is to wire in an on and off switch. Adding a manual switch to an electric radiator fan is an economical way of keeping your car cool and in good condition. Featuring wiring diagrams for single pole wall switches commonly used in the home.

Line voltage enters the switch outlet box and the line wire connects to each switch. The black wire power in source attaches to one of the switch screw terminals. Pre wired connector plugs into fan connector and the red wire is routed to the relay via an inline crimp connector. After you have pulled your switch out from the wall the wires in the box and connecting to the switch should look like one of the following.

How to wire an on off switch for an auto cool fan by justin cupler. A toggle switch can be wired into the system to manually override the cycling of the fan. A couple of decades ago it was popular to simply add a switch under the dash to control an electric cooling fan often referred to as an auxiliary fan. Tape the wires with electrical tape.

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. Or on at 195 f. Switched lines and neutral connect to a 3 wire cable that travels to the light fan outlet box in the ceiling the fan control switch usually connects to the black wire and the light kit switch to the red wire of the 3 way cable in this diagram the black wire of the ceiling fan is for the fan and the blue wire. Depending on the model the thermostat sending unit triggers the fan on at 185 f.
