1. A system for protecting a MEMS relay switch system that controls electric current to a load, the system comprising:
a parallel resonant circuit in series with the MEMS relay switch system, the parallel resonant circuit comprising an auxiliary switch in series with a capacitor configured to be pre-charged by a voltage source, and an inductor in parallel with the auxiliary switch and the capacitor, wherein the inductor is in series with the MEMS relay switch system.
