Abstract
A sensing edge for causing an object moving in a first direction to move in a second direction by actuation of a device upon force being applied to the sensing edge. The sensing edge includes a base member for being secured to the object. A first elongate wall extends from the base member to form a generally enclosed cavity. A second elongate wall extends from the base member such that the second wall is positioned within the cavity between the first wall and the base member. A switch is positioned within the cavity between the first and second walls for actuation of the device upon application of external pressure to the first wall.
