| 摘要 | 1. AN ELECTRICAL SWITCH WHICH IS CLOSED BY THE APPLICATION OF PRESSURE AGAINST AN AREA OF THE SWITCH AND IS OPENED WHEN THE PRESSURE IS REMOVED COMPRISING A. AN ELECTRICALLY NONCONDUCTIVE BASE; B. A FIRST ELECTRICALLY CONDUCTIVE LAYER POSITIONED AGAINST SUCH BASE; C. A NONCONDUCTIVE SEPARATOR MEANS PLACED AGAINST THE SIDE OF THE CONDUCTIVE LAYER OPPOSITE THE BASE, SAID SEPARATOR MEANS HAVING AN OPENING THEREIN; D. A SECOND ELECTRICALLY CONDUCTIVE LAYER PLACED AGAINST THE SIDE OF THE SEPARATOR MEANS OPPOSITE THE FIRST CONDUCTIVE LAYER; E. A LAYER OF NONCONDUCTIVE NONCOMPRESSIBLE MATERIAL PLACED AGAINST THE SIDE OF THE SECOND ELECTRICALLY CONDUCTIVE LAYER OPPOSITE THE NONCONDUCTIVE LAYER MEANS, SAID NONCOMPRESSIBLE LAYER HAVING AN ELONGATED OPENING POSITIONED ADJACENT THE OPENING IN THE SEPARATOR MEANS; AND F. A PRESSURE-RESPONSIVE DEFLECTABLE PORTION OF THE NONCOMPRESSIBLE LAYER POSITIONED ADJACENT THE OPENING CAPABLE OF BEING DEFLECTED DOWN INTO SAID OPENING WHEREBY THE APPLICATION OF PRESSURE TRANSMITTED TO AND AGAINST THE PRESSURE-RESPONSIVE DEFLECTABLE PORTION CAUSES SAID PORTION TO MOVE A PORTION OF THE SECOND CONDUCTIVE LAYER AGAINST THE FIRST CONDUCTIVE LAYER TO CLOSE THE SWITCH. |
