Patent number: 7268651Abstract: The invention relates to a electromechanical switching device having two movable contact elements interacting with a fixed contact. Said switching device has a housing. When viewing a fixing side from the top, said housing is divided into two areas bordering with a longitudinal side of the housing, one of the movable contact elements and the corresponding fixed contact being located in said areas, wherein each of the housing areas has a narrow partial area and a broad partial area bordering therewith. The broad partial area of the first housing area is adjacent to the narrow partial area of the second housing area and the narrow partial area of the first housing area is adjacent to the broad partial area of the second housing area. The actuation directions of the movable contact elements are directed opposite each other.Type: GrantFiled: April 2, 2004Date of Patent: September 11, 2007Assignee: Siemens AktiengesellschaftInventors: Gunther Eckert, Wolfgang Leitl
