    摘要： This disclosure relates to touch-sensitive mechanical keyboards and methods for detecting touch events and key depression events on the touch-sensitive mechanical keyboard. The keypad can include a plurality of domes, a plurality of key make electrodes, first touch electrodes, and second touch electrodes. The first touch electrodes may be located underneath the plurality of key make electrodes, and the second touch electrodes may not. Both touch electrodes can detect touch events based on self-capacitance sensing. A key depression event can cause the key make electrode to make electrical contact with a corresponding first touch electrode, creating a short circuit that may cause the measured signal to saturate. The keyboard can include a plurality of sensing circuits coupled to the key make electrodes, the first touch electrodes, and the second touch electrodes. The plurality of sensing circuits can be used to detect both touch events and key depression events.

    摘要： A switch device includes a circuit module and a pressing module. The circuit module includes a plurality of pushbuttons and a light-emitting member that emits light having different colors when the pushbuttons are pressed. The pressing module includes an operating unit, a driven member and a pressing member. The driven member is moved alternately to a retracted position and a projecting position as a result of depression of the operating unit. The pressing member is connected to the driven member to press one of the pushbuttons when the driven member is at the projecting position, such that one of the colors of the light corresponding to the one of the pushbuttons is visible through the operating unit.

    摘要： In a membrane-type touch panel including a pair of circuit layers having facing conductive circuit patterns normally separated by spacers defining voids through which regions of the circuit patterns can move to effect actuation, a series of projections are provided which, upon actuation, are adapted to act inwardly upon the outer surface of at least one of the two circuit layers at regions aligned with corresponding voids to reduce the required actuation force or to allow a reduction in the size of the spacer voids to reduce the possibility of false actuations.

    摘要： A printed circuit board comprising a dielectric film substrate and a plurality of circuit patterns for a capacitor switch formed on said dielectric film substrate at a certain space from each other. Each of the circuit patterns comprises a switch electrode pair formed on one surface of the dielectric film substrate, a first fixed electrode connected to one of the switch electrode pair, a first lead pattern connected to the other of the switch electrode pair, a second fixed electrode formed on the other surface of the dielectric film substrate in such a manner as to be opposed to the first fixed electrode through the dielectric film substrate, said first and second fixed electrodes forming a fixed electrode pair, and a second lead pattern connected to the second fixed electrode. A plurality of the fixed electrode pairs are arranged at an enlarged space larger than the certain space defined between the circuit patterns, and the density of the first and second lead patterns disposed in the enlarged space is reduced.
