Abstract
A signal transmitter for a filling level sensor has two sliding contacts which are manufactured integrally with a holder and with spring elements. This leads to the manufacturing costs of the signal transmitter being particularly low. The sliding contacts are arranged on spring tongues and are connected to one another via a link. The spring tongues and the spring elements are therefore arranged in a row and allow the sliding contacts to be prestressed particularly uniformly against sliding tracks of the signal transmitter.

A signal transmitter for a filling level sensor of a fuel tank, the signal transmitter configured to produce electrical signals as a function of a filling level of the fuel tank, the signal transmitter comprising:
- a filling level sensor lever arm supporting a float following the filling level of the fuel tank;
- a support for attachment of the filling level sensor lever arm to a vertical wall in the fuel tank;
- at least two sliding tracks arranged on the support;
- at least two sliding contacts arranged on the lever arm, each of the at least two sliding contacts configured to mate with a respective one of the sliding tracks;
- a spring element for preloading the two sliding contacts against the sliding tracks;
- a common bridge attached to the spring element;
- a holder for holding the spring element on the lever arm;
- and
- a spring tongue for each of the respective sliding contacts, the spring tongues spaced apart on the common bridge,
- wherein the holder, the spring element, the common bridge, the sliding contacts, and the spring tongues are manufactured in one piece.
