ABSTRACT:
A multi-switch membrane-switch assembly includes a longitudinally extending, resiliently flexible, non-conductive membrane having a convexly bowed cross section defining on an undersurface thereof a plurality of interrupted circuits defining longitudinally aligned pairs of laterally spaced, conductive contacts. A rigid substrate defines on an oversurface thereof a plurality of longitudinally aligned, conductive shorting elements. A laterally spaced pair of longitudinally extending, non-conductive positioning ribs are disposed on the oversurface of the rigid substrate. Each positioning rib defines an undercut for receiving and maintaining a longitudinally extending edge of the membrane, the positioning ribs cooperating to maintain the membrane convexly bowed.
