  • Patent number: 11078707
    Abstract: A safety contact strip for a closing edge includes an inner shell facing the closing edge and being formed by a coextrudate of a first electrically insulating plastic. An outer shell spaced apart from the inner shell is formed by a coextrudate of a second electrically insulating plastic. Switching chambers respectively retained by at least one web between the inner and outer shells are formed with the outer shell. Two switching layers spaced apart from one another are formed in each switching chamber by a coextrudate of a third electrically conductive plastic. An electrical conductor is embedded in each of the switching layers as a further coextrudate.

  • Patent number: 6888081
    Abstract: A safety contact mat has an upper mat half and a lower mat half with respective mutually facing spaced apart conductive layers, which are to be brought into contact in order to close an electrical contact. At least one of the mat halves is formed by a flat coextrudate of a non-conductive elastomer, a conductive elastomer as the conductive layer, and of a conductive woven material enclosed between the elastomers.
