At the left: under the temperature sensor of system of injection (2) the model with the 5-cylinder engine has an electronic thermoswitch (1). Scheme of an arrangement of contacts the following:
The indicator of temperature of cooling liquid operates approximately as well as the indicator of amount of fuel. Food arrives to the device at the included ignition, connection on "weight" happens via the temperature sensor on the engine. This sensor represents resistance passing the it is more than current, than temperature so the bimetallic element in the device heats up more strongly owing to what the needle deviates further is higher. In Audi two various types of temperature sensors are used.
