ABSTRACT:
A micro-electromechanical system (MEMS) switch comprises a trench formed in a substrate. A free moving conductive mass may be formed within the cavity. When the switch is moved or otherwise acted upon my an inertial force to conductive mass makes contact with a pair of electrodes partially covering the trench thus turning the switch on.
