16.2 Working principle:

Inside the brake switch, there are two mutually independent switches with one normal close and

the other normal open. After applying the accelerator pedal, the former normal close switch turns to

be normal open, while the normal open one turns to be normal close. Both signals will be sent to

ECU to be used to control other systems. Whenever the two signals disaccord, ECU will enter failure

mode, the electronic throttle will not respond when applying the accelerator pedal and the engine

will maintain idle speed working state.

Composition: the double brake switch is installed on the bracket of the brake pedal and contains two

independent switches inside.

Installation requirement: the assembly is installed on the pedal and there is a thread adjusting

mechanism on the switch for stroke adjustment of the switch and effective stroke adjustment of the

brake switch.
