Temperature Switch

Thermo switch to gasoline engines used to energize the heater and the intake manifold to the heater automatic choke. Voltage is applied to only as long as the engine coolant picks up a certain temperature. When the temperature rises above 55-65 ° C thermal switch opens, and the supply voltage is interrupted. To prevent freezing in the carburetor throttle body some carbs and installed elektropodogrevatel. One thermal switch can provide power to some parts or each part can have its own temperature switch. In the event of a suspected malfunction TH, it can be verified using the tester and thermometer. To do this, remove the thermostatic switch and put it in a cool place (eg, refrigerator). When cold, TH contacts should be open. You can check this by using a tester that is included in the measurement mode of resistance. The tester should show infinite resistance. Next you need to heat the thermal switch (you can put it in hot water). At a temperature of 55 ° or slightly above contacts must withdraw and the tester will show the resistance close to zero. If not, then, temperature switch is faulty.
