  • Irreversible switch for laminated communication device, and laminated communication device using the switch
    Patent number: 11961686
    Abstract: An irreversible power switch which is operational from the outside after lamination of laminated communication device and the like, includes a substrate, electrodes disposed on the substrate, a brittle member disposed so as to face the electrodes and apart from the electrodes and a conductive adhesive portion disposed on the brittle member at a side to face the electrodes thereof. The electrodes and the conductive adhesive portion are irreversibly and electrically bonded by brittle fracture of the brittle member under the external pressing force in the thickness direction of the laminated communication device.
    Type: Grant
