Switches & Sensors

HVAC Switches & Sensors are critical components within a vehicle's heating, ventilation, and air conditioning system, monitoring conditions and activating functions to maintain cabin comfort and regulate engine temperature. These parts transmit signals regarding temperature, pressure, airflow, and switch positions to the vehicle's control module, enabling automated climate control and essential engine management functions. Sensors are commonly found monitoring coolant temperature, refrigerant pressure, and ambient air temperature, while switches control fan speeds, mode selection, and air recirculation. Examples within this HVAC > Switches & Sensors category include temperature sensors like the MAHLE 70819125 for BMW applications, pressure switches used in MAN trucks such as MPN 81619750252, and blower motor control switches. Proper functioning of these sensors and switches ensures optimal HVAC performance and efficient vehicle operation.
