1. A safety edge for an electrically operated door, comprising:
- a female housing strip having an interior cavity in which is positioned at least one first electrical contact means;
means for attaching the female housing strip to an edge of a door; and
a male actuator strip having at least one second electrical contact means, the male actuator strip being telescopically received in the female housing strip, the male actuator strip being movable between a first position in which the second electrical contact means is spaced from the first electrical contact means and a second position in which the second electrical contact means engages the first electrical contact means to close a normally open circuit.

Abstract
A safety edge for an electrically operated door includes a female housing strip adapted for attachment to an edge of a door and a male actuator strip. The female housing strip has an interior cavity in which is positioned a first electrical contact. The male actuator strip has a second electrical contact. The male actuator is telescopically received in the female housing. The male actuator strip is movable between a first position in which the second electrical contact is spaced from the first electrical contact and a second position in which the second electrical contact engages the first electrical contact.

14. A safety edge for an electrically operated door, comprising:
-
a "C" channel female housing strip having an interior cavity, opposed ends, an interior wall, an exterior wall, and a plurality of channels disposed between the interior wall and the exterior wall, the channels extending between the opposed ends, a first electrical contact positioned within the interior cavity at both the opposed ends, wires extending along at least one of the plurality of channels connecting the first electrical contact at each of the opposed ends, each of the first electrical contacts including a positive electrical contact and a negative electrical contact in spaced relation; means for attaching the female housing strip to an edge of an automatic door; a male actuator strip having opposed ends, a second electrical contact including a bridge contact positioned at both of the opposed ends, the male actuator strip being telescopically received in the female housing strip, the male actuator strip being movable between a first position in which the second electrical contact is spaced from the first electrical contact and a second position in which the bridge contact of one of the second electrical contacts spans between the positive electrical contact and the negative electrical contact of one of the first electrical contacts to close a normally open circuit; biasing means being disposed between the female housing strip and the male actuator strip to bias the male actuator strip toward the first position; and stop means preventing the male actuator strip from being withdrawn from the female housing strip when in the first position.

15. In combination:
-
a door having an edge; a plurality of modular "C" channel female housing strips secured to the edge of the door, each of the female housing strips having an interior cavity, opposed ends, an interior wall, an exterior wall, and a plurality of channels disposed between the interior wall and the exterior wall, the channels extending between the opposed ends, a pair of first electrical contacts positioned within the interior cavity, one of the pair of first electrical contacts at one of the opposed ends and another of the pair of first electrical contacts at another of the opposed ends, wires extending along at least one of the plurality of channels connecting the pair of first electrical contacts; at least one connector comprising a plurality of connective members insertable into the plurality of channels at one of the opposed ends of each of two female housing strips to structurally and electrically connect adjacent female housing strips in end to end relation; and a plurality of modular male actuator strips, each male actuator strip having opposed ends, a pair of second electrical contacts positioned on the male actuator strip, one of the pair of second electrical contacts at one of the opposed ends and another of the pair of second electrical contacts at another of the opposed ends, one of the plurality of male actuator strips being telescopically received in each of the plurality of female housing strips, each male actuator strip being movable between a first position in which each of the pair of second electrical contacts is spaced from the first electrical contacts and a second position in which at least one of the pair of second electrical contacts engages at least one of the pair of first electrical contacts to close a normally open circuit.
