An astragal (10; 310; 410; 510) for attachment between a movable closure member (11; 111; 311; 411; 611) and a fixed surface having a sealing device and having an electrical switching device to signal engagement with an object including a retainer (15; 115; 315; 415; 615) secured to one of the closure member and the fixed surface, an elongate arcuate sealing member (30; 330; 430; 530; 630; 730; 830; 930) for engaging the other of the closure member and the fixed surface when in close proximity, the arcuate sealing member selectively affixed to the retainer, a resilient carrier (45; 345; 445; 545; 645; 745; 850; 950) disposed within the arcuate sealing member, and at least one electrically conductive strip (46; 346; 447; 547; 651; 746; 846; 946) attached to the carrier in unobstructed facing relation to an electrically conductive contact (20; 120; 320; 448; 548; 620) and temporarily movable into engagement with the electrically conductive contact when an object displaces the arcuate sealing member and the resilient carrier to effect electrical contact therebetween.
An astragal for attachment between a movable closure member and a fixed surface having a sealing device and having an electrical switching device to signal engagement with an object comprising, retainer means having an electrically conductive contact section secured to one of the closure member and the fixed surface, an elongate generally tubular sealing means for engaging the other of the closure member and the fixed surface when in close proximity, circumferential ends of said tubular sealing means selectively affixed to said retainer means at spaced locations, resilient carrier means disposed within said tubular sealing means, and electrically conductive strip means of substantially annular configuration incorporated in said carrier means in unobstructed facing relation to said contact section of said retainer means and temporarily movable into engagement with said contact section of said retainer means when an object displaces said tubular sealing means and said resilient carrier means to effect electrical contact therebetween.
An astragal for attachment between a movable closure member and a fixed surface having a sealing device and having an electrical switching device to signal engagement with an object comprising, retainer means having an electrically conductive contact section secured to one of the closure member and the fixed surface, an elongate generally tubular sealing means for engaging the other of the closure member and the fixed surface when in close proximity, circumferential ends of said tubular sealing means attached to electrically conductive strip means, and resilient carrier means attached to said electrically conductive strip means and having ends selectively affixed to said retainer means at spaced locations, said electrically conductive strip means being positioned in unobstructed facing relation to said contact section of said retainer means and temporarily movable into engagement with said contact section of said retainer means when an object displaces said tubular sealing means and said resilient carrier means to effect electrical contact therebetween.
