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.
