Abstract
A safe and convenient ON/OFF switch arrangement for a touch control bar graph device of the type which includes an array of light transmitting touch-sensitive areas superimposed over a bar graph display. In order to require two operations to enable the touch control bar graph device, the present arrangement has an ON touch-sensitive area positioned adjacent to but spaced from the touch control bar graph device. A de-energizing touch-sensitive area is positioned in the space between the ON touch-sensitive area and the touch control bar graph device. Further, a circuit means is responsive to the ON and the de-energizing touch-sensitive areas for enabling operation of the touch control bar graph device in response to the touching of the ON touch-sensitive area, and for disabling touch control bar graph operation in response to the touching of the de-energizing touch-sensitive area. As a result, if a user attempts to enable operation of the touch control bar graph device by moving a finger directly between the On touch sensitive area and the touch control bar graph device, the user's finger at least momentarily touches the de-energizing touch-sensitive area to disable the touch control bar graph device.
