The exploited idea consists in inserting an electronic switch in parallel to a light electromechanical switch in air to combine the benefits of both devices. The electronic switch is turned on and off to support the electromechanical commutations limiting their jitter and the arcs that would reduce the system lifetime. During the already performed tests, DC currents up to 20 kA were diverted in less than 100 mks with good repeatability. In case of emergency, the current can be interrupted in few tens of milliseconds. A resistor can be inserted in parallel to the switch to discharge inductive loads or to produce desired overvoltages (a voltage up to 5 kV was reached in this configuration). Specific circuits were designed to preserve the components from transient voltage overshoots. This switching system is expected to work for 10000 operations without major maintenance. The developed solutions may be extended to many relevant applications as particle accelerators and HVDC networks.
