Abstract
An electrical snap-action switch with a contact link which can be actuated via a switching plunger and a bistable spring and which is connectable in a first switching position to at least one first contact pair and in a second switching position to at least one second contact pair. The spring arrangement on both sides of the switching plunger has at least one spring arm, via which the contact link is movable transversely with respect to the movement direction of the switching plunger up to a movement end position in the event of breakage of one of the spring arms. A sliding ramp is provided in the movement path of the contact link, which sliding ramp spaces apart at least one contact of the contact link in the movement end position from the associated contact of the respective contact pair in the event of breakage of one spring arm.
