Abstract: A switch device comprises a base forming a plurality of spacing walls thereon. A plurality of receiving holes is formed on longitudinal edges of the base for receiving corresponding fixed contacts and movable contacts therein. A plurality of sliding members is mounted on the base and a cover is received over the base. A pair of locking blocks is formed at lateral sides of the base for engaging with a pair of locking slots formed at lateral sides of the cover. To aid mass production, each fixed contact comprises a contacting portion, a pair of shoulders formed on lateral edges of the contacting portion for connecting with a carrier plate and an insertion leg extending from the contacting portion. Each movable contact comprises a contacting arm, a pair of connecting shoulders connected with a carrier plate and an insertion portion extending to the opposite to the contacting arm. Each fixed contact and movable contact forms a V-cut for facilitating the process of removing the carrier from the contact plate.
