Electrical Toggle Switches

A toggle switch is a switching device comprising a plurality of terminals and means operated by a projecting leve for making and breaking electrical connections between pairs of those terminals.
Toggle switches of various types have long been used to control power in domestic, commercial, industrial, and military applications for operating various electrical devices and equipment. Toggle switches typically are manufactured with a dielectric housing that contains electrical contacts and is fitted with a manually operable handle to switch power to externally mounted terminals.

Toggle switches typically provide a manually accessible member which has metastability in a first position and a second position. A toggle switch includes a toggle lever that is mounted to a cover or housing so as to pivot about an axis or the like. A spring is placed in contact with the toggle lever to exert a biasing force to maintain the toggle lever in one or more stable positions, in addition to maintaining or assisting in the maintenance of a force on electrical contacts that are being switched into contact.
