Definitions

  • This invention relates to electric switches, and more particularly to a manually operable toggle switch of the multiple pole type.
  • lt is still another object of the present invention to provide an improved toggle switch of the ydouble pole type wherein movement of the operating member or handle positively moves the tiltable contact members with respect to the stationary or fixed contacts .to overcome any tendency to retard the action of the tiltable Contact members and insure their movement to either position with a snap and positive action.
  • lt is a more specic object of this invention to provide an improved toggle switch of the double pole type having the parts thereof so constructed and arranged and being relatively small so as to provide a switch of the so-called miniature type which is adapted to meet 2,757,252 Patented July 31, 19,56
