1. A microelectromechanical systems (MEMS) switch device, comprising:
a movable plate movable between an open position and a closed position, wherein the MEMS switch device is activated by a magnetic force moving the movable plate to the closed position;
shunt operable to conduct current when the movable plate is in the closed position; and
an inductive coil electrically coupled to the shunt, wherein an electrical field flux in the inductive coil being greater than a calibrated threshold indicates an overcurrent condition in the shunt and de-activates the MEMS switch device by moving the movable plate to the open position.
