Abstract
A micromechanical switch and a method of making the switch. The micromechanical switch of the invention is made by surface micromachining techniques and include an isolated contact located on the beam and separated from the main body of the beam by an insulated connector. The isolated contact provides the advantage that the current flow caused by the circuit being switched does not alter the fields or currents used to actuate the switch. Thus, the present invention allows the actuation functions to be unaffected by the signals that are being switched.
