Definitions

  • the object of this invention is to provide a multicontact relay which is economical to manufacture in quantity.
  • Known multi-contact relays have required considerable adjusting work to be done to the contact springs all of which require considerable time and the labor cost required for such adjustment added to the expense of the relay.
  • One of the features of this invention resides in dispensing with individual adjustment of the tension of the several contact springs. This feature is achieved by arranging the movable contact springs in an array each of the contacts having its longitudinal axis in a common plane, without pretensioning said springs, said springs receiving their operating contact pressure by a single contact operating member mounted on a plurality of pretensioned resilient elements.
  • One of the advantages realized from the construction of a relay in accordance with this invention lies in the fact that the arrays of contact springs may be manufactured as an integral stamping, to be molded into position and after to be separated into individual units without the necessity of any further individual contact spring tensioning adjustment.
  • said base further comprises a plate, a pair of insulating members, means to attach each of said members to opposite edges of said plate, one end of each of said fixed contacts firmly atfixed to one of said insulating members and 5 one end of each of said movable contacts firmly aflixed to the other of said insulating members.
