Implementations of the subject matter described herein provide a switching apparatus. The switching apparatus includes: a switching component including a first main shaft, which is adapted to selectively connect and disconnect at least one circuit in response to the rotation of the first main shaft; and an operating mechanism including a second main shaft for actuating the first main shaft to rotate via the second main shaft; wherein the switching component further includes a first interface, and the operating mechanism further includes a second interface, and the second main shaft to be detachably coupled to the first main shaft in response to the engagement of the first interface and the second interface.

Switching apparatus

A switching device including: a body which has a first side wall and a first end wall, the first side wall being perpendicular in relation to a longitudinal direction, and the first end wall is substantially perpendicular to the first side wall; and a first fixed contact comprising an inner section and an outer section, the inner section having a thickness dimension, the outer section protrudes from the first side wall in the longitudinal direction. The first fixed contact includes a test terminal which is integral to the inner section and protrudes from the inner section in a lateral direction, which is perpendicular to the longitudinal direction and an end wall plane defined by the first end wall, the test terminal having a substantially planar test terminal surface, and the test terminal has a thickness dimension which is parallel to the thickness dimension of the inner section, the thickness dimension of the test terminal is substantially smaller than the thickness dimension of the inner section, the test terminal is accessible from outside the body from the direction of the first end wall, and the test terminal is adapted to be connected to a female connector.

Switching device whose stationary contact is provided with test terminal

The electrical switch includes three fixed contacts and a rotatable knife contact being connected with a permanent electrical connection to a third one of the fixed contacts and including at least one pair of longitudinal blades. The rotatable knife contact connects in a first switching position only a first one and a third one of the fixed contacts electrically together, and in a second switching position only a second one and a third one of the fixed contacts. The rotatable knife contact connects further in a zero switching position the first, the second and the third fixed contact electrically together.

Electrical switch with three fixed contacts, a rotating knife contact and three switch positions

The electrical switch includes a first and a second fixed contact, and a movable knife contact including at least one longitudinal pair of blades being flexibly connected to each other, wherein the blades form, in a switching event, contact with contact portions of the first and/or the second fixed contact. Opposite surfaces of the contact portions of the first and the second fixed contact include a roughened area and the inner surface of each blade includes a protruded area or opposite surfaces of the contact portions of the first and the second fixed contact include a protruded area and the inner surface of each blade includes a roughened area.

Electrical switch

The electrical switch includes a first and a second fixed contact, and a rotatable knife contact including at least one pair of blades being flexibly connected to each other and rotating around a rotational axis. A third fixed contact is positioned on an opposite side of the rotational axis in relation to the adjacent first and second fixed contact and a middle portion of the rotatable knife contact is electrically connected to the third fixed contact. The rotatable knife contact connects in a first switching position the first fixed contact and in a second switching position the second fixed contact to the third fixed contact.

A change-over switch including a frame having a first side wall and a second side wall, a first supply terminal, a second supply terminal, a load terminal, and at least one gas flow opening for discharging gasses from the frame. The second side wall faces substantially opposite direction relative to the first side wall. The change-over switch is adapted to selectively provide a first connection between the first supply terminal and the load terminal, and a second connection between the second supply terminal and the load terminal. The first supply terminal and the second supply terminal project from the first side wall, and the load terminal projects from the second side wall. The at least one gas flow opening is formed in the second side wall.

Change-over switch

The electrical switch includes two fixed contacts and a rotatable knife contact having a rotational axis and including at least one longitudinal pair of blades flexibly connected to each other. The two fixed contacts as well as the blades in the rotatable knife contact are of a first electrically conductive material composition. The first and the second fixed contact includes a first contact pin and outer ends in the blades in the rotatable knife contact includes a second contact pin. The first contact pin and the second contact pin are of a second electrically material composition, which is different from the first material composition. The first contact pin and the second contact pin pass over each other during a switching event.

Electric switch

Panel for transfer switch

A stationary contact for a rotary switch is provided. The stationary contact includes a connection portion for connecting to a conductor and a first portion being a contact portion for connecting the stationary contact to a rotary contact. The stationary contact also includes a second portion being a support portion for supporting the stationary contact to a switch body. The contact portion and support portion extend in the same angle from the connection portion. A method of mounting a rotary switch is also provided.
