Abstract
A sensing edge for causing a closing door to open by actuation of a device upon force being applied to the sensing edge includes an elongate outer sheath for being attached to a door. The sheath is fabricated of a material which is compressible upon application of an external pressure. An interior surface of the sheath defines an area for receiving a portion of a switch means. A pair of flexible members extend from the exterior surface of the sheath away from the door and toward one another. Mounting walls extend from a different portion of the exterior surface of the sheath for receiving an edge of the door.
