Pressure switch

A pressure switch senses changes in the pressure of a fluid, such as engine oil or air pressure in a tire, and sends an electrical signal to the vehicle’s control system to indicate the level. It is often used as a safety device to alert the driver of low oil pressure or tire pressure, and can also be used to control various systems in the vehicle, such as the fuel pump or air suspension. The switch is typically installed on the engine block or tire valve stem and is connected to the vehicle’s electrical system to monitor and control pressure levels.
