Definitions

  • the cover 1 includes a pair of support feet 14, which with the lateral terminals 7, 7a and central terminal 10 form struts for fixing of the cover 1 on the support plate 4 by means of lips 15, 15a.
  • the lips 15, 15a are folded and crimped on the plate 4.
  • the central member 60 is compressed elastically between the truncated cone housing 62 and the friction of these conical surfaces against each other creates a turning force proportional to the angle of the cone.
  • the force is sufficiently great in order to prevent the displacement of the slider under the effect of shocks and vibrations.
  • a potentiometer device comprising in combination: a conductive cover formed as a single piece molding with a central terminal; a baseplate of insulating material fixed on said cover by means of lips folded and crimped on said plate; a resistance track and collector printed on said baseplate, said collector having an aperture in which is engaged a projection of thecentral terminal, said resistance track having apertures in which are engaged projections of 'at least one pair of lateral terminals, at least one rotor of insulating material; at least one slider, said slider being operatively associated with said rotor and in contact with said resistance track and said collector.
