ABSTRACT:
A closure-sensitive signalling device with a cantilever switch responsive to the opening of a folded article such as a business card holder, greeting card, folder, or other article having panels foldable with respect to each other along a fold line. The cantilever switch has a stationary electrical contact and a conductive cantilever arm engageable therewith, and is mounted along with a battery-powered signal generator IC on a low-profile printed circuit board adapted for mounting on one panel of the folded article with the cantilever switch adjacent to the fold line. The cantilever arm's free end is engageable with another panel of the folded article such that the switch is held open when the article is closed and is closed when the article is open. The signalling device generates an audible or visible signal in response to a signal from the signal generator IC.
