ABSTRACT:
In an electric desired-value transmitter for automotive vehicles, particularly as electric gas pedal, having an actuating element and a potentiometer the wiper of which is coupled to the actuating element, a switch which is also coupled with the actuating element is connected to a comparison device to which the output voltage of the desired-value transmitter and at leasst one comparison voltage are fed. When the actuating element is in that position in which the switch is actuated, the comparison device is preferably fed two comparison voltages, one of which lines somewhat below the value of the output voltage which is given off by the desired-value transmitter upon proper operation and the other of which lies somewhat above said value.
