    摘要： An electrical switch mat which includes an electrical contact, a support frame, and a plate member. The electrical contact is operable under pressure between a closed condition and an open condition and is maintained in either the opened or closed condition in the absence of pressure. The support frame defines a two-dimensional area and is formed with a protective housing to prevent excessive compression from being transmitted to the components of the electrical contact during activation. The plate member is sized to fit within the two-dimensional area of the support frame and is supported at its perimeter by the support frame. The plate member transmits activating compression to the electrical contact. The electrical contact can be a ribbon switch that may either run substantially continuously or be placed intermittently along the perimeter of the plate member. The ribbon switch includes a pair of vertically spaced electrical conductors enclosed in an insulative jacket such that the conductors are urged into electrical engagement upon compressing the plate member to activate the ribbon switch. The protective housing is generally channel shaped and the electrical contact is positioned within the channel.

    摘要翻译： 一种电开关垫，其包括电触点，支撑框架和板构件。 电接触件可在闭合状态和打开状态之间的压力下操作，并且在没有压力的情况下保持在打开或关闭状态。 支撑框架限定了二维区域，并且形成有保护壳体，以防止在激活期间过度压缩被传递到电触点的部件。 板构件的尺寸设计成适合于支撑框架的二维区域内，并且通过支撑框架在其周边处被支撑。 板构件将激活压缩传递到电接触。 电触点可以是带状开关，其可以基本上连续地运行或沿着板构件的周边间歇地放置。 带状开关包括一对垂直间隔的电导体，封闭在绝缘套管中，使得当压缩板构件以致激活带状开关时，导体被推动成电接合。 保护壳体通常为通道形状，并且电触头位于通道内。

    摘要： A normally-closed electrical switch having a plurality of electrically conductive contacts normally arranged in overlapping electrical communication. A preferred embodiment of the present invention also comprises a pressure directing mechanism for directing and actuating pressure to specific portions of the electrically conductive elements. The normally-closed electrical switch of the present invention interrupts an electrical circuit in response to an applied pressure.

    摘要： An illuminated, press-at-any-point switching device which can be actuated by the application of or the removal of pressure at substantially any point along a surface of the switching device. The illuminated, press-at-any point switching device includes a cover, an illuminating member, a switching assembly and a mounting surface. The cover holds the components of the device onto the mounting surface. The device may also include a separate signal indicia to indicate the operation of the device.
