What is the Cruise Control Clutch Release Switch all about?

Manual transmission vehicles equipped with cruise control operate similarly to automatic transmission vehicles. The buttons operate the same way, except in one case: manual transmission vehicles are equipped with a clutch pedal. If you’ve driven a manual transmission vehicle, you are aware that when you're driving a constant speed and press the clutch pedal in without releasing the accelerator, the engine races to much higher RPMs. The exact same thing would happen if the cruise control did not use a switch to cancel the current set speed when the clutch pedal is pressed in. For that reason, a cruise control clutch release switch is mounted on the clutch pedal. It is a small electrical switch that is open and does not complete a circuit when the clutch pedal is pressed in, meaning the cruise control will not set, or will cancel if it is set. When the pedal is not pressed in, the circuit is closed and there is continuity, so the cruise control will be able to set. If the cruise control clutch release switch has failed in the open position, your cruise control will not set at all. If the release switch has stopped working while in the closed position, your engine will race when the clutch is depressed while the cruise control is set, and you will need to use another function to shut down the cruise control set speed.
