Definitions

  • the present invention relates to a contact spring set for electromagnetic relays and similar connecting apparatus.
  • the object of the invention is to render a careful assembly of the separate springs in such spring sets possible by using a small number of simple and cheap details.
  • the spring set shown in Fig. 1 comprises for instance ten contact springs 10, which are supported by two side plates H and I2 of insulating material. Said side plates stretch from the back end of the springs to alongside the contact places.
  • I 2 In the center part of each one of both side plates H, I 2 there are three rows, each with ten holes l3, l4 and I5, respectively, and at the rear edge a further row with ten slots 16.
  • the contact springs are fastened in the holes l3, l4 and the slots IS in a manner, which will be described more closely with reference to Fig. 4.
  • the stationary springs in a set i. e.
