Electric Cooling Fan Switches
 by: Darren Dunner


The work of these electric cooling fan switches is to sense the temperatures in the car engine environment and then turn on the cooling fan if cooling is needed. Different electric cooling fan switches have different temperature settings in order to enable the required operation when it reaches a desired temperature. You can set the different temperatures accordingly as per your vehicle needs.

The system of the electric fan turns on automatically when it detects any change in the temperature of the engine goes over a set point with the help of a thermostatic fan switch. It will stop when the temperature returns to normal. A thermostatic fan switch that is used by the electric cooling fan is no more than a sensor. At times, even a thematic fan switch is also used which is a mechanical switch placed inside the radiator hose to detect cooling system temperatures. A thermal switch and relay is a type of fan switch very similar to thermatic switches which allow operations thermally and when the air conditioner is in use.

An electronic thermal switch is a mechanical switch that will detect temperatures of the incoming air and is mounted on the front of the radiator core.

It is normal for your cooling fan not to run all the time. The electric cooling fan is only needed when the engine's temperature rises above a set level or when running your air conditioner. Running the cooling fan would be waste of electrical energy when it is not needed.

Electric cooling fans can be found on most autos with transverse mounted engines, most front wheel drive vehicles, and on many late model rear-wheel drive vehicles. They are used on FWD vehicles because the fan won't require a belt drive and can be mounted independently of the engine location. Best yet, electric fans require less power for operation, which provide for improved fuel economy and performance. They are quieter and provide more precise cooling.
