Product Overview

The brake light switch, OEM number BN7N-66-490A, is the stop lamp switch fitted across an unusually broad range of vehicles, including the Mazda 2, 3, 5, 6, CX-3, CX-5, CX-9, and MX-5 Miata, the Ford C-Max, Edge, Escape, Expedition, Explorer, F-150, F-250, F-350, Flex, Focus, Fusion, Mustang, Taurus, and Transit, the Lincoln Continental, MKC, MKS, MKT, MKX, MKZ, and Navigator, the Mercury Mariner, Milan, and Mountaineer, the Volvo V50, and the Toyota Yaris, spanning model years 2004-2025. Since this single switch spans six brands and dozens of models, it's a genuinely essential, high-turnover part for anyone stocking universal electrical components.

Worn or failing units typically show up as brake lights that won't turn on, the gear shift lever getting stuck in park, cruise control failing to cancel properly, or the engine failing to crank on vehicles with a shift-lock interlock tied to the brake switch. GSK Auto manufactures this switch to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

(Confirm against your VIN or chassis code before ordering - this switch spans six brands and vehicles with both manual and automatic transmissions, and cruise control equipment can affect which exact variant is needed, so it's worth double-checking the exact model and equipment before ordering at volume.)

What Is a Brake Light Switch?

Function: The brake light switch detects when the brake pedal is pressed and sends a signal to illuminate the brake lights, and on many modern vehicles also feeds signals to the cruise control system and the shift-lock interlock that prevents shifting out of park without the brake pedal depressed.

Working Principle: Mounted near the top of the brake pedal, the switch is mechanically triggered by pedal movement, closing or opening an electrical circuit that signals the brake lights, cruise control module, and shift interlock solenoid depending on the vehicle's systems.

Importance: Because this single switch often feeds multiple vehicle systems beyond just the brake lights, a failing switch can cause a cluster of seemingly unrelated symptoms, from non-functioning brake lights to a stuck gear shifter or cruise control that won't disengage.

Common Failures & Signs: Internal contact wear or mechanical failure affecting switch operation. Brake lights that won't illuminate when the pedal is pressed. Gear shift lever getting stuck in park, unable to shift into gear. Cruise control failing to cancel when the brake pedal is pressed, or the engine failing to crank on vehicles with a shift-lock interlock.
