Cabin Temperature Sensor / Switch: Description and Operation

In-Car Temperature Sensor

The in-car temperature sensor with aspirator blower (B10/4) serves for measuring the temperature in the vehicle passenger compartment.

The in-car temperature sensor is equipped with an aspirator blower which continuously sucks air out of the vehicle passenger compartment for measurement of the temperature.

It is connected to the pushbutton control module by a separate electric lead.
The aspirator blower provides continuous circulation of the interior air around the in-car temperature sensor to ensure a high degree of control accuracy.
