Abstract: An electrical switch comprises a pair of spaced terminals, fixed in an insulating housing; a metal roller; and, a finger-piece for moving the roller between first and second switching positions engaging only one and both terminals respectively. The one terminal is resiliently flexed to bias the roller against the second terminal in the second switching position. The one terminal comprises a cantilever spring having an upset end protruding into the roller path and providing the fulcrum for an overcenter action biassing the roller in either switching position.
