Want to know how an automotive brake light switch works? The following
article describes the basic operation and wiring of the switch. This switch controls when the brake lights go on
and off as the brake pedal is depressed by the driver. This is achieved by the
switch plunger resting
against the pedal arm.
A stop light switch is designed in the opposite way of a normal switch would work
because when the switch is has contact by the pedal it is off, and when pedal is
the switch is on. Through time and usage the contacts inside the switch become worn and
can burn and short out rendering the
switch non operational.
