Abstract

A sheet switch (142) has a bottom layer (144) and a top layer (160). First and second conductors (148, 162) located on the bottom layer (144) form two separate conductive paths, with a voltage potential applied to the conductors (148, 162). The top layer (160) includes a ground conductor (172). Spacers (178) are positioned between the top and bottom layers (160, 144). When forces are externally applied, the spacers (178) collapse and the ground conductor (172) contacts the first and second conductors (148, 162), and establishes a conductive path therebetween.
