    • A signal transformer for a switching signal for operating a digital integrated circuit (10) such as a microcomputer, in a motor vehicle, uses a resistor (3) in series between the supply and the switch (101) to produce the signal. The signal is fed via a low-pass filter (102) to the circuit (10) and a voltage limiter (103) restricts the voltage fed to the circuit (10) to the operating voltage. The limiter (103) includes a diode (6) whose anode is coupled to the signal voltage and whose cathode is connected to the operating voltage (SV) of the integrated circuit (10). There may be a Zener diode (11) whose anode is to the earth and whose cathode is to the signal voltage, the Zener voltage lying close to the integrated circuit operating voltage. A voltage divides (8,9) may be immediately in front of the integrated circuit (10).
