Electrical terminations for cermet resistance elements

Claim 1

IN A ROTARY POTENTIOMETER EMPLOYING A CERMET RESISTANCE ELEMENT AND SO CONSTRUCTED TO PREVENT ARCING BETWEEN THE MOVABLE CONTACT OF A POTENTIOMETER AND THE CERMET RESISTANCE ELEMENT TO THEREBY AVOID DELETEIOUS EROSION OF THE CERMET RESISTANCE MATERIAL, AND FURTHER HAVING A VERY LOW END RESISTANCE AND A SUBSTANTIALLY UNIFORM TORQUE OVER A 360* ROTATION OF THE POTENTIOMETER WIPER, SAID POTENTIOMETER COMPRISING, A HOUSING; A NON-CONDUCTIVE SUPPORT BASE MOUNTED IN SAID HOUSING; A CERMET RESISTANCE ELEMENT AFFIXED TO SAID SUPPORT BASE; A NON-CONDUCTIVE BRIDGE AFFIXED TO SAID SUPPORT BASE BETWEEN JUXTAPOSED ENDS OF SAID CERMET RESISTANCE ELEMENT, SAID BRIDGE PROVIDING AN ELEVATED PLANAR SURFACE SUBSTANTIALLY COPLANAR WITH THE SURFACE OF SAID CERMET RESISTANCE ELEMENT, SAID NON-CONDUCTIVE BRIDGE BEING WIDER THAN THE WIDTH OF THE ENDS OF SAID CERMET RESISTANCE ELEMENT; AN ELECTRICAL TERMINATION FOR THE RESPECTIVE ENDS OF SAID CERMET RESISTANCE ELEMENT COMPRISING CONDUCTIVE ELEMENTS RESPECTIVELY DISPOSED BETWEEN THE ENDS OF SAID RESISTANCE ELEMENT AND A JUXTAPOSED SIDE OF SAID NON-CONDUCTIVE BRIDGE AND MAKING ELECTRICAL CONTACT WITH SUBSTANTIALLY THE ENTIRE END CROSS-SECTIONAL SURFACE OF SAID CERMET RESISTANCE ELEMENT, SAID ELECTRICAL TERMINATION BEING AFFIXED TO THE SIDE OF SAID NONCONDUCTIVE BRIDGE AND EXTENDING LATERALLY BEYOND THE PROJECTED EXTENT OF SAID RESISTANCE ELEMENT; AN ELECTRICAL CONDUCTOR AFFIXED TO SAID ELECTRICAL TERMINATION AT A POINT BEYOND THE END SURFACE OF SAID CERMET RESISTANCE ELEMENT; AND A MOVABLE WIPER CONTACT MOUNTED IN SAID HOUSING FOR TRAVERSING SAID RESISTANCE ELEMENT, SAID CONTACT MOVING FROM THE CERMET ELEMENT TO THE ELECTRICAL TERMINATION BEFORE A DISCONTINUITY BETWEEN THE WIPER AND CERMET ELEMENT OCCURS THEREBY AVOIDING ANY ARCING BETWEEN THE WIPER AND THE CERMET RESISTANCE ELEMENT.
