Abstract: A bypass switch provides a bypass path between a first terminal and a second terminal. The bypass switch includes: a first set of electrical contacts respectively connected to the first terminal and the second terminal; a second set of electrical contacts respectively connected to the first terminal and the second terminal; and a movable member. The movable member includes a first conductive section, a second conductive section and an insulator between the first conductive section and the second conductive section, wherein the movable member is movable from an initial state, via a first state, to a second state, wherein in the initial state the first set of electrical contacts are conductively separated and the second set of electrical contacts are conductively separated, in the first state the first set of electrical contacts are conductively connected via the first conductive section and the second set of electrical contacts are conductively separated, and in the second state the second set of electrical contacts are conductively connected via the second conductive section.

Abstract: An electrical switchgear for fast limitation and interruption of fault currents includes a fixed electrode, a movable electrode having a contact portion and a repelling portion, a plurality of contact fingers, and a coil. The coil is arranged adjacent to the repelling portion to induce eddy currents therein, the coil and the fixed electrode being arranged on the same side of the movable electrode, and the repelling portion being movable relative to the coil. The coil has a first dimension between two of its opposite lateral ends and defines an area which corresponds to a majority of a surface area of the repelling portion. The repelling portion provides a continuous current path, having a dimension corresponding to the first dimension, for eddy currents induced by the coil, whereby the movable electrode is pivotally thrown in a direction away from the coil and the fixed electrode, thus providing a circuit trip.

Abstract: A bypass switch provides a bypass path between a first terminal and a second terminal. The bypass switch includes: a first contact device; a second contact device; and a plunger being moveable from an initial state, via a first state, to a second state, wherein in the initial state the first terminal and second terminal are conductively separated; in the first state a movement of the plunger causes the first contact device to close a first conductive connection between the first terminal and the second terminal; and in the second state the plunger mechanically forces the second contact device to close a second conductive connection between the first terminal and the second terminal.
