Abstract
In a switch device, suitable for use as active sensor in an automotive vehicle, wherein current through a load can be switched as a function of a physical variable acting on the switch device, two terminals of the switch device can be connected together via a semiconductor switch. They also form the input of a current supply circuit. A sensor produces an electric signal which represents the physical variable and which can be fed to a threshold circuit. The semiconductor switch is controllable in pulsating manner as a function of the output signal of the threshold circuit.
