ABSTRACT:
In an electrical desired-value transmitter, particularly for an electronic gas pedal system, a return spring (5) as well as a force elastic jump spring (15) arranged parallel to it are provided. The desired-value transmitter has an electric path converter which gives off an electrical desired-value signal. In order to verify the proper operation of the return spring, a contact spring (9) of a first safety switch contact (10) acts on it in such a manner that the force of the return spring is transmitted to the contact spring. In the event that the return spring is broken, the safety switch contact assumes a position which is characteristic of this and gives off a corresponding signal which can reduce the output of the engine. The electric path converter may be a potentiometer.
