A low-cost, easy to manufacture and maintain pressure responsive switch. The switch includes a pressure responsive diaphragm made from latex rubber that is mounted in a housing base. An annular groove in the housing base communicates with an annular shoulder in a housing cover to compress an O-ring for forming upper and lower chambers, sealing the housing and securing the diaphragm.

Pressure responsive switch and method of making same

A sensing edge is provided for causing a door to open by actuating a device upon force being applied to the sensing edge. The sensing edge includes an elongate outer sheath with a first strip of resiliently compressible material affixed to one of the inner surfaces. A first strip of flexible, electrically conductive material is affixed to the strip of resiliently compressible material. A second strip of flexible, electrically conductive material is supported on the opposite inner surface of the outer sheath. The second strip of conductive material faces the first strip of conductive material, with a space being provided between the first and second strips. The first and second strips of conductive material form a sensor for detection of an external force applied to the sheath, whereby the first strip of resiliently compressible material is adapted to allow displacement of the first strip of flexible, electrically conductive material when the outer sheath is folded for shipping to prevent cracking of the first strip of flexible, electrically conductive material. An L-shaped conduit which is pivotally installed in the upper surface of the outer sheath is also provided, to allow the same sensing edge to be used in left hand or right hand applications.
