    Abstract: A plurality of individually folded cards, each bearing indicia relating to the location of individual switches of a switch array, is hingedly attached to a housing. Selection means is provided for selecting one of the cards so that the certain of the cards become stacked in a region of the housing and the selected card unfolds across the switch array. Registration means may be provided for fixedly positioning the selected card with respect to the switch array. The cards may be translucent so that light emitting indicators associated with the switches may be viewed through the selected card.

    Abstract: LEDs are arranged in a matrix and driven by a pair of registers. A column register sequentially enables the columns of LEDs and a row register selectively operates the LEDs of each column in accordance with a predetermined binary code. A color control and a brightness control circuit may be included in connection with the row register to selectively control driving currents to the LEDs to control color hue, and to selectively control the duration of ''''on'''' time to control apparent brightness.

    Abstract: A touch entry switch array comprising a layer of non-conductive material is sandwiched between two conductive layers. Orthogonally disposed conductors are arranged in a matrix and adapted to make electrical connection by deforming an upper resilient, transparent or translucent layer through respective apertures to establish electrical contact. Indicator means is provided to indicate through the apertures the actuation of the associated switch. In one form of the device, the orthogonal conductors are supported on the lower layer and the upper layer is constructed of transparent or translucent conductive material which may be deformed through the apertures to operate the associated switch. In another form of the invention, one set of conductors is supported on the upper layer to be deformed through the apertures to contact conductors on the lower layer.
