Brake light switch 2007 H2

Can someone explain how the brake light switch works? It is attached to the brake pedal , but I don’t see any plunger that would activate the switch when the pedal is pushed.

Welcome.

All vehicle specific Tech Questions go in the Vehicle Sections....... H2 Questions belong in the H2 Section.

Hint: Electronic parts (sensors) do not need a plunger.

my 03 has a plunger but it is pinned to the brake pedal with a dowl and clip.

in this case the black slider is the plunger. you can take them apart and clean them carefully.

Thank you for the information. I took the old switch apart and now I understand how it works. The Hydraboost rod pushes against the middle of the switch where there the rectangle top of the switch is.
