Abstract

See full text

An electrical switch has a fixed contact and a moving contact arranged for movement between an ON position in contact with the fixed contact and an OFF position out of contact with the fixed contact, and an operating member for operating the moving contact. A spring co-acts between the operating member and the moving contact and resiliently biases the moving contact towards each of the ON and OFF positions through an over-centre action of the spring. An end piece is fitted at each end of the spring, which has a formation, for example, a groove, for pure rotary engagement with a part, for example, a pin, movable with the operating member or moving contact for imparting resilient action upon the operating member or the moving contact.
