Abstract

An objective of the present invention is to provide a switch whereby a roughening of an electrode surface is avoided and reliability is high. To resolve the problem a switch comprises a plurality of switch parts (2, 3) each further comprising a fixed electrode and a moving electrode which is positioned opposite the fixed electrode and either closes or opens vis à vis the fixed electrode. The plurality of switch parts (2, 3) carry out an input and a blocking of a current which flows through the switch. The plurality of switch parts (2, 3) is electrically connected in series. Furthermore the plurality of switch parts (2, 3) are formed such that after one of the switch parts (3) is closed the other switch part (2) is closed.
