Abstract
A fluid level sensor that is particularly useful in fluid fuel tanks of motor vehicles wherein a resistor network is arranged on a fixed support and it is possible to generate an output signal from the resistor network which corresponds to the position of a float member. The level sensor has particularly low wear and is inexpensive to produce with a contact structure for the resistor network that operates through interaction of a magnetic member is moved by the float and can be deflected such that an electrical connection is dependent on the position of the float.
