Abstract

A switch includes a contact having at least two contact springs and at least one slide for moving the at least two contact springs in opposite directions between an open position and a closed position of the contact. Movement in opposite directions ensures a long service life of the contact elements at the contact springs and provides sufficient contact pressure.
