1. A method of maintaining performance of a micro-electromechanical switch, said method comprising:

  • measuring a performance parameter of the switch; and

    upon detecting switch performance below a predetermined lever settable by the user of the switch, initiating corrective action by applying at least one of;

    a time-varying voltage configured to induce a scrubbing action between contacts of the switch; and

    a modified control voltage profile for operating the switch, wherein the modified control voltage profile comprises at least of;

    a different shaped profile; and

    an off voltage applied at a different magnitude.
