Patent number: 8063334Abstract: The switching device of at least one embodiment includes at least two switching contacts for interruption of a current path, with the switching contacts being arranged in a quenching chamber in order to quench an arc which is struck on opening. The quenching chamber opens into a gas outlet channel for overpressure which is produced during the striking of the arc to escape from. A pressure sensor for pressure detection is provided in the gas outlet channel and trips a switching mechanism, which is at least indirectly connected thereto, of the switching device on reaching a predeterminable pressure value. According to at least one embodiment of the invention, the gas outlet channel includes a Venturi nozzle. A reduced pressure, which is created in the Venturi nozzle as the gas flow passes through, is detectable by way of the pressure sensor.Type: GrantFiled: January 14, 2009Date of Patent: November 22, 2011Assignee: Siemens AktiengesellschaftInventor: Jörg-Uwe Dahl
