Abstract: A switch system includes a mechanical switch for electrical currents. The mechanical switch operates in a conductive state and in a non-conductive state. A first actuator is configured to change the state of the mechanical switch, wherein an actuation of the first actuator is based on a Thomson coil system. A second actuator is also configured to change the state of the mechanical switch and includes a loaded spring system locked by a latch system. Each of the first and second actuators is configured to change the state of the mechanical switch depending on a property of an electrical current passing through the mechanical switch.

CPC classification number: H01H33/04 ,  H01H33/42

Abstract: A switching device for low-voltage or medium-voltage applications including: one or more electric poles; for each electric pole, at least a fixed contact and at least a movable contact, each movable contact being reversibly movable between a coupled position, at which the movable contact is coupled with a corresponding fixed contact, and an uncoupled position, at which the movable contact is separated from the fixed contact, wherein a separation gap is present between the movable contact and the fixed contact, when the movable contact is in the uncoupled position. The switching device includes, for each electric pole, at least an arc-diverting element made of electrically insulating material.
