The Temperature Switch 195 On / 175 Off from DeWitts Radiator is a crucial engine management component designed for builders and mechanics seeking precise cooling control. This thermal switch activates cooling fans or auxiliary systems at 195°F and disengages at 175°F, helping to maintain optimal operating temperatures for various engine types.
Operating on a simple mechanical principle, this switch uses a bimetallic element that expands and contracts with temperature changes. It closes a circuit when coolant reaches 195°F and opens it again at 175°F, utilizing a hysteresis design to prevent relay chatter and extend component life by reducing on/off cycling.
Ideal for automotive enthusiasts, restoration shops, and performance builders, this switch allows for the integration of modern cooling logic into classic vehicles and custom engine swaps. Its compact design—measuring just 1.35 x 0.9 x 3.2 inches and weighing only 0.08 lbs—facilitates installation in tight engine bays without obstruction.
