The brake light switch is a car component essential for the proper functioning of your brake lights when you apply the brake. The brake light switch has many names, such as stoplight or brake switch. It is used to manage the opening and closing of the electrical circuit managing the brake lights.
Thus, when the driver presses the brake pedal, he actuates the push button of the brake switch, which closes the circuit and therefore triggers the ignition of the brake lights, and they turn on. When the brake pedal is released, the switch push button is then released and closes the electrical circuit. The brake lights go out at this time.
