    摘要: An alternating current switch suitable for automatic assembly is provided having an insulating housing including an open top base and a cover to close the base. The base has side openings to expose screw terminals and may have bottom openings to admit wires to push in connectors. The terminals are integral parts of contact arms within the housing. The contact arms as well as a balance spring are held in place in the housing within side wall slots integral with the base of the housing and by bosses integral with the cover. The balance spring and a movable contact arm are shaped to bear against cam portions of a toggle.The cover is provided with bearings to hold the toggle at its trunions in pivoting relation and is provided with a top opening through which the trigger of the toggle extends to the switch exterior. Ease of assembly is achieved due to the small number of parts and the simplicity of the individual parts so that the switch may be assembled quickly by hand or in automatic assembly equipment of relatively low cost.The movable contact is formed from a single metal strip including wire terminal and electrical contact and has a long operational life.
