Abstract

A capacitive touch switch arrangement is provided which alleviates panel layout problems which result from the minimum area required for proper operation of capacitive touch switches. There is at least a pair of capacitive touch switches, each having, as its input element, a touch pad (84 to 89) of sufficient area for proper operation of the touch switch. A pair of primary touch sensitive areas (58, 60, 62, 64, 66) are delineated, such as by panel indicia 69 to 77, and arranged such that a touch on either primary touch sensitive area activates only one of the respective touch switches. In addition, at least one secondary touch sensitive area (59, 61, 63, 65) is delineated and arranged such that a touch on the secondary touch sensitive area activates both of the adjacent touch switches. A circuit means responsive to the touch switches includes decoding logic for generating different outputs in response to the touching of each of the touch sensitive areas. Thus, there is not a one-for-one correspondence between all of the touch sensitive areas and the touch pads. In particular, there are more delineated touch sensitive areas than touch pads, and the touch sensitive areas may be smaller in area than the touch pads. <IMAGE>
