True Tech Ignition TS601T Engine Cooling Fan Temperature Switch

The True Tech Ignition TS601T is an engine cooling fan temperature switch designed to monitor coolant temperature and activate the cooling fan at the proper temperature threshold. This precision-engineered thermal switch ensures optimal engine cooling system performance by providing accurate temperature-based fan control.

Key Features:

• Bimetallic contact arm design for precise temperature sensing and switching action
• Factory-calibrated to activate at specified lower-temperature set point
• Each unit is tested to confirm proper switch actuation at rated temperature
• Custom wax formulation expands when heated to activate snap-action electrical contact
• Direct replacement for OEM part numbers including 1J0959481A, 007800111, and others
• Complete quality control throughout manufacturing process

This temperature switch utilizes creep action technology with two fused metals that expand at different rates, providing reliable and precise performance. The switch transfers electrical signals to the fan controller when coolant reaches the specified temperature, protecting your engine from overheating damage.
