Patent ID: 7332835

Claim:
A system comprising at least one switching module comprising: switching circuitry comprising at least one micro-electromechanical system switch for selectively establishing a current path from an input line to an output line of the switch in response to a gate control signal applied to the switch; control circuitry coupled to the switching circuitry to supply the gate control signal to the micro-electromechanical system switch; and power circuitry coupled to the control circuitry and the switching circuitry, wherein the power circuitry comprises an input terminal pair and an output terminal pair galvanically isolated from one another, wherein a module power input signal received through the input terminal pair is electrically referenced to the input line of the switch, and a module power output signal supplied through the output terminal pair is electrically referenced to the output line of the switch so that the module output power signal is unaffected by a voltage that develops across the input and output lines of the micro-electromechanical system switch when said switch is set to an open state.
