<p>A safety edge (20) for an electrically operated door includes a female housing strip (22), a male actuator strip (24) and means (32) for attaching the safety edge (20) to an edge (34) of the door (36). The female housing strip (22) has an interior cavity (30) in which is positioned a first electrical contact (52). The male actuator strip (24) has a second electrical contact (70). The male actuator strip (24) is telescopically received in the female housing strip (22). The male actuator strip (24) is movable between a first position in which the second electrical contact (70) is spaced from the first electrical contact (52) and a second position in which the second electrical contact (70) engages the first electrical contact (52) to complete a normally open circuit.</p> |
