In layman's terms...the battery is supplying the radiator fan with power, continuously BUT the "thermo switch" keeps the circuit broken until the fan is needed. Basically the two or 3 wires running "into" the switch "do not" connect on the inside UNTIL the right temperature is achieved.
Then on the inside the of the switch, once heated, causes enough power to let a device inside, to move and allow the circuit to be completed.
This allows the "already on" power to make the fan come on.
If you want to test the switch....just take off the wires to it and touch them....if the fan comes on, then chances are it is the switch that is faulty. If the fan does not come on then....there is a problem in the wiring circuit.
Many things can lend to a default in wiring such as a broken fuse, bad relay or broken wiring connection.

Why is a thermal switch often included on the control circuit for a glow-coil pilot burner ignition?
Thermal switch is to cut off the pilot ignition circuit when the heater temperature is beyond a set temperature. The thermal switch limits the temperature and protects the heaters
How does the fan work?
If the question is about the motor fan or engine fan, the main function of this fan is cooling the radiator of the engine which in turn is cooling the water circulating inside the engine unto the radiator and back. This keeps the engine at a fairly operable temperature without overheating and damaging damaging its parts.
Will it still work when my radiator fins for CPU cooler are damaged?
That will depend on the degree of the damage to the fins. If some of the fins are slightly bent there should be no problem at all. On the other hand if several of the fins are broken off the cooling will probably not be adequate, Is the microprocessor's internal temperature sensor reporting an unusually high temperature (this is the easiest way to tell if cooling is working right or not)?
How do slide switch work?
Slide Switches work on the principle of connecting disconnected parts to each other. The 'switch' connects two parts allowing the current to pass through it. Ash.
What is a device made of semiconductor material that acts like a switch controlling the flow of electrons in a chip?
if a diode is in forward biased the diode acts as switch is on and when we apply the diode in reverse biased then it work as the switch as off.
Where is the radiator cooling fan switch on a 90 olds ceira with a 3.3?
there's no switch, it has a temperature sensor.
What is a engine temperature cooling switch?
The engine temperature cooling switch helps regulate the engine's temperature. Teemed with the radiator and incoming air, this keeps the engine at its optimal performance temperature.
What is a thermo switch?
A thermoswitch is the device by the radiator, that switches on the fan as soon as the engine/ radiator reaches a set temperature
Where is the temperature switch located on a 2002 Toyota solara?
Please edit your question to be more specific. Which temperature switch? Radiator fans? Air conditioning? Other?
What components measures the temperature of the coolant and turns the radiator fan on and off to keep the coolant at a certain set temperature?
the coolant temperature switch
Why won't the radiator van start to work when i gets hot on my Nissan Serena 1994 van?
If it's a electric fan, it sound like the temperature switch is bad
Blower motor suddenly stopped?
check the blower fuse, temperature sensor on the radiator,switch on the dashboard and the blower relay switch.
If the ac gas have low presure then radiator fan doesnot work without ac?
Generally, on most vehicles, the radiator fan is controlled by a thermostatic/electric switch. When the coolant temperature rises to the setpoint, the switch closes, applying electric current to the fan, turning it on. Then, when the coolant temprature has cooled below the setpoint, the switch opens, turnng the fan off.
What does a vehicle thermostat do?
It regulates the temperature of the water in the radiator and tells the fan when to switch on to start cooling or to switch off if its too cool. Engines have an optimum running temperature, and the Thermostat helps keep it at that.
If temperature gauge not working can it be the reason for the radiator fan not run?
Ummmm, Radiator fans run off a temperature switch. Sometimes they put the fan switch and sender for the gauge together so I suppose it could be related. Have you checked to see if the wires are unplugged? Just a thought.
1996 where is the ECT sensor Camry 1996?
The ECT or the Engine Coolant Temperature Sensor is a switch. This switch is located on the bottom of the radiator in the 1996 Camry.
How does the Honda CR-V radiator fan motor work?
There are two motors which drive two separate fans on the CR-V radiator. One is the regular cooling system fan and it is operated by a temperature sensing switch in the coolant system that monitors the coolant temperature. When the coolant reeaches a certain temperature the temperature sensing switch turns on the current to the cooling fan. When the coolant temoperature falls below a certain temperature the switch shuts the fan off. The other fan is the fan that is controlled by the vehicle cabin air conditioner. When the A/C is turned on the fan comes on automatically with the a/c.
