ABSTRACT:
An electrical switch mat which generally includes a first layer of flexible matting material, a second layer of flexible matting material, and a perimeter ribbon switch disposed between the first layer and the second layer. The ribbon switch has a longitudinal edge and is operable under pressure between a closed condition and an open condition and maintained in one of the open and closed conditions in the absence of pressure. The first and second layers have a peripheral edge which is aligned with the longitudinal edge of the ribbon switch in a coplanar relationship to form a peripheral edge of the electrical switch mat.
