Frequently Asked Questions
Q: What is SW-2154 and what vehicles does it fit?
A: SW-2154 is a Motorcraft OEM brake light switch assembly designed for Ford vehicle brake systems. Do not use this part for electric lift truck applications. This switch is specific to Ford automotive brake circuits only.
Q: What are the voltage and current specifications for SW-2154?
A: SW-2154 operates at 12VDC and is rated for 10A resistive load. It features a SPST momentary contact configuration designed for brake light circuits in Ford vehicles with blade connectors.
Q: What materials are used in SW-2154 housing and actuator?
A: SW-2154 has a molded thermoplastic composite housing with a steel actuator pin that is nickel-plated for corrosion resistance. These materials provide durability in automotive underhood and brake pedal environments.
Q: What is the mechanical cycle life rating for SW-2154?
A: SW-2154 is rated for a minimum of 100,000 mechanical cycles, suitable for the repeated brake pedal actuations expected over the vehicle service life. This ensures reliable brake light operation.
Q: How do I know if SW-2154 brake light switch needs replacement?
A: Replace SW-2154 if brake lights remain on constantly, do not illuminate when brakes are applied, or flicker intermittently. These indicate internal contact failure or worn actuator surfaces in the brake light switch assembly.
