Patent ID: 6872902

Claim:
A micro-switch, comprising: a first substrate and a second substrate bonded together to form a cavity; on the first substrate, at least one signal path that runs from inside the cavity to outside the cavity at at least two locations; and at least one movable structure on the second substrate, said movable structure comprising at least one conductive contact area, wherein at least one portion of said movable structure is inside said cavity, and the movable structure is moved in response to a force provided by an actuator, wherein a state of electrical contact of said micro-switch is changed by moving said movable structure, wherein said actuator is powered through at least one actuator drive line and at least one ground line, wherein said at least one actuator drive line and said at least one ground line run from inside said cavity to outside said cavity, said at least one actuator drive line being electrically connected to said actuator and said at least one ground line being electrically connected to an electrical common.
