Abstract
A system is presented. The system includes a micro-electromechanical system switch. Further, the system includes a balanced diode bridge configured to suppress arc formation between contacts of the micro-electromechanical system switch. A pulse circuit is coupled to the balanced diode bridge to form a pulse signal in response to a fault condition. An energy-absorbing circuitry is coupled in a parallel circuit with the pulse circuit and is adapted to absorb electrical energy resulting from the fault condition without affecting a pulse signal formation by the pulse circuit.
