Claim:
1. A capacitance switch comprising a first plate including a magnet, a second plate, and a plurality of micro-posts extending from the first plate and having uniform dimensions, the plurality of micro-posts having a dielectric coating deposited thereon, wherein during an “off” state the plurality of micro-posts are in spaced relation with the second plate, and wherein radio frequency power is transmitted between the first and second plates through the plurality of micro-posts when in an “on state”, and wherein during the “on” state the plurality of micro-posts contact the second plate creating a homogeneous capacitive contact with the second plate across the plurality of micro-posts and capacitively coupling the first plate with the second plate, wherein a capacitive value of the homogeneous capacitive contact is a function of the number of individual micro-posts in contact with the second plate.
