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.

Switching unit for an electrical switch, and electrical switch

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.

Electrical switching device, especially circuit breaker

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.

Switching unit for an electrical switching device

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.

Switching device

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.
