Patent number: 10403458Abstract: A switching unit for an electrical switch is disclosed. In an embodiment, the switching unit includes at least one fixed contact and one moveable contact with a current feed, which in order to close or open the current path are respectively brought into mechanical contact with each other or mechanically or magnetically separated from each other. The switching unit further includes at least one extinguishing plate, which affects an electrical arc created when the electrical contacts are opened. The current feed to the moveable contact is designed such that in the open position it directs the current along the electrical arc in the opposite direction to the current direction of the arc.Type: GrantFiled: July 26, 2017Date of Patent: September 3, 2019Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Reinhard Herdegen, Michael Poles

Patent number: 9111695Abstract: An electrical switching device includes a switching mechanism, a housing element, a cover element and a test button, which is movable between a non-actuated position and an actuated position. When the test button is moved from the non-actuated position into the actuated position, the switching mechanism disconnects at least one moveable contact from at least one fixed contact of the switching mechanism. Further, a blocking element is movable between a first position and a second position, so that the blocking element, when the cover element is closed, is held by the cover element in the first position against a pre-tensioning force in the direction of the second position. Further, when the cover element is opened, the blocking element moves the test button from the non-actuated position into the actuated position.Type: GrantFiled: December 10, 2012Date of Patent: August 18, 2015Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Thomas Bunk, Reinhard Herdegen, Siegfried Pirker

Patent number: 9064657Abstract: A switching unit for an electrical switching device, in particular for an electrical power circuit breaker, is disclosed and includes a breaker mechanism with an operating lever and a switching mechanism which can be actuated by the operating lever. In at least one embodiment, at least one breaker assembly board is included, onto which the breaker mechanism is fixed. The at least one breaker assembly board includes at least one positioning lug which is designed for positioning the switching unit in a housing of the electrical switching device.Type: GrantFiled: January 29, 2013Date of Patent: June 23, 2015Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Thomas Bunk, Reinhard Herdegen, Siegfried Pirker

Patent number: 9053887Abstract: A switching device is disclosed, in particular an electrical circuit breaker, including a housing and a switching unit disposed inside the housing. In at least one embodiment, the housing includes an openable housing cover with a switching opening through which a control lever head, which can be moved between an on-position and an off-position, of a control lever for switching the switching unit projects. The switching opening includes an opening contour and the control lever head includes an outer contour, which are aligned with one another such that the control lever head in the on-position prevents any movement of the housing cover via the control lever head, and in the off-position permits a movement of the housing cover via the control lever head.Type: GrantFiled: January 23, 2013Date of Patent: June 9, 2015Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Abel Alejandro Castaneda Arriaga, Ronald Cone, Reinhard Herdegen, Ekkehard Plechinger, Reinhard Steger

Patent number: 6483062Abstract: A push-pull switch includes an actuating mechanism whose actuating tappet is engaged in a thread in the handle. By this arrangement, a pulling movement on the handle is converted into a rotational movement of the actuating tappet. As such, balls mounted as latching elements in the actuating tappet can be released gently from a secure latching position in the ON state.Type: GrantFiled: July 26, 2001Date of Patent: November 19, 2002Assignee: Siemens AktiengesellschaftInventors: Reinhard Herdegen, Peter Weiss, Rudolf Zimmermann

Patent number: 5684670Abstract: A control switch with a holder is to be provided which can simply and quickly be secured by one person to a variable-thickness fitting plate. To this end the rose (9) of the control switch has a longitudinal groove (11) and a transverse groove (12). The holder which can be fitted on the rose (9) consists of a lower casing (14), a securing ring (5) and an upper casing (23). The lower casing (14) and the securing ring (5) have matching pitches (20, 6) so that when the securing ring (5) is rotated via a toothed spindle (7) fitted off-center it is axially shifted. After the holder has been fitted on the rose, when the securing ring (5) is rotated, a partial thread (18) fitted thereto is rotated out of the longitudinal groove (11) into the transverse groove (12) and thus pressed by the simultaneous axial movement of the partial thread (18) against the limiting edge of the transverse groove (12) taking the form of a thread segment (13).Type: GrantFiled: August 9, 1995Date of Patent: November 4, 1997Assignee: Siemens AktiengesellschaftInventors: Rudolf Zimmermann, Rainer Kreutzer, Reinhard Herdegen, Josef Birzer
