Described herein is a switching apparatus for low or medium voltage electric grids, which includes one or more electric poles. Each electric pole includes: an outer casing defining an internal volume of the electric pole; a fixed contact assembly accommodated in the internal volume of the electric pole and including a fixed contact member extending along a longitudinal axis of the electric pole; at least one movable contact assembly accommodated in the internal volume of the electric pole; an actuation member accommodated in the internal volume of the electric pole and arranged coaxially and externally relative to the fixed contact member, so that the fixed contact member passes through the actuation member along the longitudinal axis. The actuation member is slidingly movable along the fixed contact member. When moving between the first and second actuation positions, the actuation member transiently couples to each trip mechanism to actuate the trip mechanism.

A power relay having terminal tabs includes an on-off contact element having at least one movable contact and at least one stationary contact, an on-off drive element, at least two pairs of input/output terminal tabs, and at least one pair of control terminal tabs. The on-off drive element makes the movable contact come into contact with or separated from the stationary contact. The two pairs of input/output terminal tabs are electrically connected to at least one pair of input/output portions of the on-off contact element. The one pair of control terminal tabs is electrically connected to control terminal portions of the on/off drive element. Each of the input/output portions is electrically connected to two of the input/output terminal tabs, which are arranged side-by-side in their thickness direction and in vicinity with each other. The input/output terminal tabs and the control terminal tabs have a same thickness and width.

A load break tool for opening a high load electrical switch having a first switch contact and a second switch contact. The load break tool includes a main body extending along a longitudinal axis between a first end and a second end. The main body is movable between an extended configuration and a retracted configuration. A first contact is coupled to the first end and configured to selectively couple with the first switch contact. A second contact is coupled to the second end and configured to selectively couple with the second switch contact. In the retracted configuration the first contact is in electrical communication with the second contact. A spring assembly is mounted in the main body for biasing the main body to the retracted configuration, the spring assembly including a compression spring.

A flexible switch has a deformable body and a plurality of electrodes, at least one of the electrodes being provided on the deformable body. The switch has a first state in which the electrodes are spaced apart and a second state in which the electrodes are in electrical contact, and the switch is configured to allow movement between the states when a force is applied to or removed from the deformable body.

An electrical switch including a neutral contact adjustment system adapted for adjusting a position of a neutral contact opening surface relative to at least one phase contact opening surface such that the neutral contact adjustment system has a first operating state which is adapted to provide a simultaneous break operation in which a movable neutral contact disconnects simultaneously with at least one movable phase contact during an opening event, and a second operating state which is adapted to provide a late-break operation in which the movable neutral contact disconnects later than the at least one movable phase contact during the opening event.

A controller is provided for use in a wet environment such as an ablutionary setting. The controller includes a base member, an input member, a seal extending between the input member and the base member, and a sealed internal volume defined at least partially by the base member, the input member, and the seal. The input member is moveable relative to the base member between a neutral position and a control position. The seal biases the input member towards the neutral position.
