Definitions

  • FIGS. 6 and 7 there is illustrated another alternative embodiment of a potentiometer in accordance with the present invention.
  • the potentiometer includes, for the most part, structure similar to that of FIGS. 4 and 5.
  • This external electrical connection is provided by a lead 55 having a cup-shaped bearing surface "56 which receives an extension 57 of the rotor 58.
  • rotor 53 is preferably a metallic electrically conductive member.
  • the rotor head 47 is therefore 'an electrically non-conductive material such as Teflon or the like to insulate the Wiper arm from the casing 41.
  • a stop ring member 118 Disposed axially between the upper end of the sealing cap 112 and the portion N9 of the base support member 80 is a stop ring member 118 which has the form generally of a short .hollow cylinder with an outer diameter equal approximately to that of the surface 114' of the sealing cap 112. The inner diameter of the ring stop member 118' is approximately equal to that of the upper portion 100. Disposed on the inner surfaceof the ring stop member 118 is a stopping block 120 which extends radially inwardly for a small fraction of the diameter of the ring stop member 118. The particular shape and function .of the stopping block 120 will be discussed in further detail in connection with the subsequent figures.
