Method for making rheostats
Abstract
Abstract THE DISCLOSURE RELATES TO A METHOD FOR MAKING RHEOSTATS. A SUBSTRATE IS PREPARED FOR SUPPORTING A RESISTIVE PATTERN WITH A FIRST CONDUCTIVE MEMBER AT ONE END, THE SUBSTRATE INCLUDING A SECOND CONDUCTIVE MEMBER FORMING AN ELECTRICALLY COMMON CONNECTION. A CONDUCTIVE MEANS IS POSITIONED OVER THE SUBSTRATE, THE CONDUCTIVE MEANS INTEGRALLY SUPPORTING A WIPER ELEMENT AND A TERMINAL PAIR. THE WIPER ELEMENT IS ROTATABLY SECURED TO THE SUBSTRATE, SO THAT ONE END MAKES ADJUSTABLE AND CONTIGUOUS CONTACT WITH THE RESISTIVE PATTERN, WHILE THE OTHER END IS ELECTRICALLY CONTINUOUS WITH THE ELECTRICALLY COMMON CONNECTION. THE TERMINAL PAIRS ARE THEN SECURED TO THE FIRST AND SECOND CONDUCTIVE MEMBERS, AND FINALLY THE TERMINAL PAIRS AND THE WIPER ELEMENT ARE SEVERED FROM THE CONDUCTIVE MEANS WHERE THEY ARE INTEGRALLY JOINED.
