A motion sensing apparatus comprises two substrates, contact means, and at least one electrically conductive element. A first substrate contains an electrically conductive layer disposed on one of its major surfaces. A second substrate contains a hole, including an interior surface that extends from one major surface to another, such that a cavity is formed by the planes of the major surfaces and the interior surface. The second substrate is positioned substantially parallel to the first substrate, such that the electrically conductive layer is positioned within an area defined by the hole. The contact means and the electrically conductive element are placed within the cavity, such that a motion sensing signal is produced when the electrically conductive element comes in contact with both the contact means and the electrically conductive layer.
