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.

A switch system, comprising:
- a mechanical switch for electrical currents, the mechanical switch comprising a conductive state and a non-conducive state;
- a first actuator configured to change a state of the mechanical switch, wherein an actuation of the first actuator is based on a Thomson coil system;
- a second actuator configured to change the state of the mechanical switch, the second actuator comprising a loaded spring system locked by a latch system;
- a conductive bridge between a first conductor and a second conductor retained in a conductive state position by a conductive plate spring,
- wherein each of the first actuator and the second actuator is configured to change the state of the mechanical switch depending on a property of an electrical current passing the mechanical switch,
- wherein the loaded spring system is configured to move independently of a Thomson conductive plate of the Thomson coil system,
- wherein the loaded spring system is configured to push the Thomson conductive plate to open the conductive bridge after the loaded spring is unlocked by the latch system.
