<p>A capacitance membrane switch (1) of the type including (a) a variable capacitor defined by a first capacitor plate (64) on a flexible film layer (60) and a second capacitor plate (52) on a dielectric film layer (50) with an air gap therebetween, and (b) a fixed capacitor defined by the second capacitor plate (52) and a third capacitor plate spaced therefrom by the dielectric film layer (50), characterized in that:
the third capacitor plate consists of conductive adhesive (47) bonded to the dielectric film layer (50) on a surface (59) thereof opposite from the second capacitor plate (52).</p> |
