    摘要: Embodiments described herein are directed towards a keypad stiffener and a method for manufacturing. The method may include forming a metal plate form. The metal plate form may include a metal grounding plate, at least one detachable island and at least one bridge. A bridge may mechanically connect the metal grounding plate to the detachable island. The method may also include forming a non-conductive molding mechanically coupling the metal grounding plate and the at least one detachable island and electrically disconnecting the detachable island from the metal grounding plate. Furthermore, subsequent to the electrically disconnecting, the at least one detachable island may be electrically floating with respect to the metal grounding plate.

    摘要: Un commutateur du type à capacitance comprend une paire d'organes à capacitance, comprenant chacun premièrement un matériau isolant (10, 11), deuxièmement un élément conducteur (14, 16) sur une surface du matériau isolant, et troisièmement un film diélectrique (15, 17) sur l'élément conducteur. Au moins l'un des organes à capacitance est mobile. En outre, les organes à capacitance sont supportés en alignement espacé généralement parallèle. Les éléments conducteurs (14, 16) se font face et sont en alignement général les uns avec les autres, et les films diélectriques (15, 17) sont mutuellement adjacents mais espacés les uns des autres. Le mouvement de l'organe à capacitance mobile pour s'engager dans l'autre organe à capacitance amène le film diélectrique (15) sur l'organe à capacitance mobile à s'engager dans l'autre film diélectrique (17) de l'autre organe à capacitance, provoquant une augmentation dans la capacitance entre les éléments conducteurs des organes à capacitance.

    摘要: @ A membrane switch panel has a printed circuit base board (20) carrying bare copper electrical circuitry (26) and contacts (26 & 28). A flexible, non-elastomer, laminar membrane (22) overlays the board (20) and also carries a bare-copper contact (24). An electrically insulating spacer (3) is provided between the board (20) and the membrane, but it is provided with an opening to allow the contact (24) upon local depression of the membrane to bridge the contacts (26 & 28) in the base board (20).
    The membrane (22) is adhesively sealed to the base board (20) enclosing an atmosphere of limited tarnishing ability for the contacts (20, 26 & 28) to maintain a low contact resistance and allow non-precious metals to be used for contacts.
