Abstract

An electric switch assembly (1) comprising a pair of terminals (3b, 3c) for connection to an electric circuit, an operator mechanism (5) for actuating the switch assembly (1) to and from a switched state in which a pathway for electric current is defined between the pair of terminals, and a magnet (19, 21) exerting a magnetic force. The switch assembly (1) may be operable away from, and/or to, the switched state by way of a mechanical snap-action, and the switch assembly is arranged such that the magnetic force enhances the mechanical snap-action.
