The Wilwood stop light pressure switch is a dual-pole switch with a 1/8-27 male pipe inlet that closes at approximately 60–100 psi. Plated steel construction and its switch action are used in Wilwood combination proportioning valve assemblies such as part number 260-11179, providing the brake-pressure sensing function needed to operate stoplight circuits on compatible systems.
