DISPOSITIVO AUTOMATICO PER RIDURRE IL CONSUMO DI ENERGIA ELETTRICA DA PARTE DI UN LUNOTTO TERMICO

摘要

A control relay (7, 5) for a heated rear window (3) is piloted by an electronic control circuit (9, 11, 15); the current-flow through a resistor (11) causes a decrease in its ohmic resistance, which leads to the cutting-off of the transistor (15), which interrupts the supply to the heated rear window (3).
