Abstract

The auxiliary switch has a pair of fixed contacts (3,4) within a housing. A pair of movable contacts (9,10) are formed at the ends of U-shaped spring contact carriers (11). The opening and closing of the contacts is made using a common slide element. This has a double ramp element such that one contact pair is closed while the other is open.
