A switch including a first electrical terminal, the first electrical terminal including a blade pivotable between an open position and a closed position, and a rod extending from the first electrical terminal parallel to the blade. The switch further includes a second electrical terminal configured to receive the blade when in the closed position, the second electrical terminal including a vacuum interrupter, wherein the vacuum interrupter engages the rod when in the closed position. Rotating the first electrical terminal in a first direction causes the blade to disengage from the second electrical terminal at a first point, and further rotating the first electrical terminal in the first direction causes the rod to disengage from the vacuum interrupter at a second point.

A method for assembling a switching apparatus for medium voltage electric systems is provided. The method includes, for each electric pole of the switching apparatus, providing a mounting assembly. The mounting assembly includes a support structure, a vacuum interrupter, a motion transmission mechanism, and an auxiliary contact. The method further includes providing a first semi-finished structure of the switching apparatus, where the first semi-finished structure includes, for each electric pole of the switching apparatus, a first pole terminal and a first fixed contact electrically connected to the first pole terminal. The method further includes, for each electric pole of the switching apparatus, installing the mounting assembly on the first semi-finished structure.

A switch may include a first electrical terminal, the first electrical terminal including a blade configured to move between an open position and a closed position, and a rod extending from the first electrical terminal, wherein the rod includes a rod receiving portion, and wherein the rod is configured to move between a first position and a second position. The switch may include a second electrical terminal configured to receive the blade when in the closed position, the second electrical terminal including a vacuum interrupter, and a vacuum interrupter rod, wherein, during a closing of the switch, while the blade moves from the open position to the closed position, the rod receiving portion engages the vacuum interrupter rod, thereby moving the rod receiving portion from the first position to the second position.

The present disclosure relates to a switching apparatus comprising one or more electrical poles, wherein for each electric pole, the switching apparatus comprises a first fixed contact electrically connected to a first pole terminal, a second fixed contact electrically connected to a second pole terminal and a third fixed contact electrically connected to a ground terminal. The switching apparatus further comprises a movable contact, which is reversibly movable about a corresponding rotation axis so that said movable contact can be coupled to or uncoupled from one or more of the above-mentioned fixed contacts, and a vacuum interrupter. An auxiliary contact is electrically connected to said fixed arc contact and a contact lever is electrically connected to said auxiliary contact and reversibly movable about a corresponding second rotation axis. The contact lever is couplable to said movable contact to electrically connect said movable contact to said auxiliary contact.
