1. In a device for the transmission of the position of a control element (particularly a gas pedal, which control element is actuatable by the vehicle driver and controls the traveling speed of a motor vehicle, the gas pedal being connected with an electrical position encoder) to an actuator via electrical transmission means, the actuator being coupled with a regulating member, particularly a throttle valve, which regulating member controls the fuel-air mixture of an internal combustion engine, the vehicle including a unit effecting a rotational speed change of the engine, the improvement whereina pedal contact is coupled with the control element,a regulating member contact is coupled with the regulating member,said pedal contact and said regulating member contact are arranged in a logic circuit arrangement, the latter being connected with the unit, said unit constituting means for effecting a rotational speed reduction of the internal combustion engine,said pedal contact and said regulating member contact are arranged in said logic circuit arrangement such that the rotational speed of the internal combustion engine is reduced with a non-actuated control element, but with a simultaneous position of the regulating member in a gas position,said pedal contact is constructed as a normally open contact, said normally open contact is closed with the control element actuated,said regulating member contact is constructed as a normally closed contact, said normally closed contact is open in the gas position of the regulating member,a line is connected to said unit,said pedal contact and said regulating member contact are arranged in parallel to one another in said line, said line is closed for normal operation of the internal combustion engine by at least one of said contacts being closed, said means reducing the rotational speed of the engine when said line is open when all of said contacts are open,said unit which causes a reduction of the rotational speed is a fuel pump relay connected to said line.
