  • Patent number: 7528337
    Abstract: A first resistor layer is formed on the lower surface of a base in film form, and at the same time, a second resistor layer in which particles of different particle diameters are dispersed is formed and layered on the lower surface of the first resistor layer, and thus, a pressure sensitive conductive sheet is formed. In this configuration, the second resistor layer in uneven form makes contact with the fixed contacts in accordance with a pressing force so that electrical connection is made via the second resistor layer and the first resistor layer, and therefore, a thin panel switch with little fluctuation in the resistance value resulting from repeated operation where a stable resistance value can be gained can be realized.

  • Patent number: 7525062
    Abstract: A capacitive proximity and/or contact sensor has an electrically conductive plastic body, which is disposed between an electrically insulating cover plate and an electrically conductive contact surface of a carrier plate disposed at a distance therefrom. The contact surface can be connected to a gating circuit, through which a change in a capacitance of a condenser formed by the cover plate, the plastic body and the contact surface as a result of proximity and/or contact of a contact region of the cover plate by an element, having a potential different to the potential of the contact surface, can be ascertained and evaluated. The plastic body is configured as a plug-in and/or clamp part and by plugging-in or clipping on the or by clamping on the carrier plate is connected form lockingly and/or force lockingly to the latter and thus to the contact surface.

  • Patent number: 7511242
    Abstract: A sensor element for a touch switch device has a sensor element body of elastic, electrically conductive material. The sensor element body has two parallel end wall areas as the top and bottom surfaces, which are integrally connected in one piece by inwardly cambered side wall areas. Such a sensor element body can be very easily compressed. The wall thickness of the wall areas is substantially the same throughout. Such sensor elements can be constructed by forming a linear strip of such material having a cross section as described, where the strip is cut into individual pieces, thereby forming each individual sensor element.

  • Publication number: 20090068857
    Abstract: A contact element for the intermittent contacting of conductor tracks on a circuit board, in particular, for flexible touchpads, for example for flexible input devices in the automobile industry, is made from a metal foam. The metal foam may be at least partly infiltrated by an elastomeric material which can also be the material of construction of the touchpad. The contact element has a very reliable construction which is particularly suitable for high voltage application. A method for production of the contact element, touchpads/input devices with such contact pads and the use of the contact pads is also provided.

  • Patent number: 7304860
    Abstract: A printed circuit board with thin film switches for a keyboard including an upper board having multiple circuit lines, an insulating separation defining multiple through holes, a lower board having multiple circuit lines and multiple thin film switches mounted on the upper and lower boards. The thin film switch has two thin film conductive elements respectively formed on the upper and lower boards and correspond to one of the through holes in the insulating separation. Each thin film conductive element has a center conductor, at least two outer conductors formed adjacent to the center conductor, and at least two conductive lines connected to the center and outer conductors. With such an arrangement, the areas of the center and outer conductors will be reduced, surfaces of the conductors are even in the curing procedure of fabricating upper or lower board to keep a stable touching sensitivity.

  • Patent number: 7259341
    Abstract: A tamper switch actuator is used in combination with a circuit board held between two outer structural members. The tamper switch actuator includes a suspended displacement member moveable to a conducting position after a given amount of compression of a compressing member. The compressing member cooperates with an outer protecting sleeve and is positioned within and moveable in the axial direction of the sleeve. The tamper switch actuator separates the outer protecting sleeve from the displacement member. With this arrangement the electrical conducting surface of the displacement member can quickly respond to separation of the casing to produce a non-conducting condition or tamper indicating conditions while remaining protected within the outer protecting sleeve.
