  • Patent number: 6396010
    Abstract: A safety edge switch for a motorized door includes a longitudinally extending base, a resiliently deformable material, an electrode array of a plurality of spaced apart conductive segments, and an array of bridging members. The switch is normally in the closed configuration. Contact with an object in the path of the moving door causes one or more bridging members to break contact with the corresponding electrode segments, thereby forming an open circuit and sending a signal to the door control system to stop or reverse the movement of the door.
