Abstract

A pyrotechnic switch for switching off and establishing electric circuits includes a first electrical conductor, a second electrical conductor, and an ignition element. In a first state of the pyrotechnic switch, the first electrical conductor and the second electrical conductor are electrically connected to one another, wherein a target separation point between the first electrical conductor and the second electrical conductor is provided. The target separation point is separated as soon as the ignition element is triggered, wherein the pyrotechnic switch is provided with a third electrical conductor. In the first state of the pyrotechnic switch, the third electrical conductor is electrically separated from the second electrical conductor and from the third electrical conductor, and in a second state of the pyrotechnic switch, the third electrical conductor is electrically connected to the second electrical conductor.
