A snap switch having an activating plunger which, when depressed, establishes an operative connection with a return spring, and causes the tensioning of a spring force accumulator. A ferromagnetic anchor is mounted pivotable about an axis running at right angles to the direction of the plunger. The anchor forms a jump member and is a component of a magnetic clamp arrangement containing a permanent magnet. The anchor activates at least one movable contact. The jumping action is initiated in both switching directions by the creation of an air gap between the anchor and its respective abutting surface in the magnet clamp. The magnetic clamp arrangement is formed by at least one yoke by way of which a magnetic circuit is closed in both positions of the anchor.
