Abstract
A sensing edge having increased sensitivity is disclosed. The sensing edge is for causing a closing door to open by actuation of a device upon force being applied to the sensing edge. The sensing edge comprises a compressible outer sheath having a grooved wall surface and at least a portion of a switch assembly positioned within the sheath. The grooved wall surface renders the sheath more easily compressible thereby increasing the sensitivity of the sensing edge.
