Abstract
Micro capacitive switches and methods of manufacturing micro capacitive switches at variable nominal capacitance value using micro-structures on the contact plates of the same dimension. In a preferred embodiment, a separately manufactured contact plate can be mounted to a movable magnet in order to be actuated to 'on' and 'off' state of the capacitive switch. Depending on the contact plate's surface condition, variable contact capacitance at “on” state can be precisely specified by geometrical properties of the micro-structures on the surface, such as the density, size and depth.
