Patent number: 8864530Abstract: The invention relates to a jack having a switch mechanism SW of the single-butt contact type in which an ON/OFF operation is performed by insertion/extraction of a plug P. When the plug is inserted, a displacement load is applied by the separator to a middle portion in the length direction of the movable contact piece to flex the movable contact piece while setting a basal end portion of the movable contact piece as a fulcrum, whereby a tip end portion thereof is contacted with the stationary contact piece. Thereafter, the middle portion in the length direction of the movable contact piece is flexed while setting the tip end portion as a fulcrum, to apply a contact pressure on a contact. As a result, miniaturization of the jack, and reduction of the production cost can be realized.Type: GrantFiled: March 16, 2007Date of Patent: October 21, 2014Assignee: Hosiden CorporationInventors: Yutaka Uno, Koji Matsumoto
