Detailed Description

Standard Ignition TS-483 is engineered for cooling system service where accurate fan engagement matters. The switch uses a thermal element that responds to heat, transferring the electrical signal to the fan controller at the specified temperature. Its factory calibration helps ensure the switch closes at the intended lower-temperature set point, while the bimetal contact design supports repeatable operation under demanding underhood conditions. This part cross-references Four Seasons 36478 for the same application.
