Patent number: 7688175Abstract: A controllable electronic switch for, e.g., controlling power distribution comprises a deformable member such as a bimetal arm that can be deformed to break an electrical path. The deformable member may be anchored at one end and in controllable contact with an electrical conductor at the other end. A heating element, such as a coil, can be used to selectively heat the deformable member. The controllable electronic switch can alternatively comprise a deformable member that is terminated in a wedge-shaped member. When the deformable member bends in response to being heated, the wedge-shaped member forces apart a pair of contacts thus breaking an electrical path. The wedge-shaped member and/or associated structures may be configured as a cam mechanism with multiple latching positions.Type: GrantFiled: August 31, 2007Date of Patent: March 30, 2010Assignee: I/O Controls CorporationInventor: Jeffrey Ying
