Definitions

  • Terminals 16, 18 are mounted by insulators 16', 18' in member 14.
  • Terminal 16 has integral therewith a terminal 20 and terminal 18 has secured thereto a fixed contact 22 for cooperation with a movable contact 24 carried by a lever 26 pivotally and slidably mounted on a frame 28 by means of a pin 30 secured to the frame 28 and extending through a slot 32 in the lever 26.
  • a spring 34 is wound about pin 30 and is provided with a biasing arm 36 bearing against lever 26 and reaction arms 38 hearing against the frame 28.
  • a toggle mechanism comprising a first lever pivotally and slidably mounted on a frame, a second lever pivotally mounted on the frame, a pair of levers pivotally connected to each other and to said first and second levers respectively, means for locking said pair of levers against pivotal movement with respect to each other, and means for unlocking said locking means to permit pivotal movement of said pair of levers with respect to each other, said locking means comprising a forked lever pivotally carried by one of said pair of levers, a pin received in the fork carried by the other of said pair of levers, and means holding the forked lever against pivotal movement.
  • a toggle mechanism comprising a first lever, link means pivot-ally mounting said lever on a frame, a second lever pivotally mounted on the frame, a pair of levers pivotally connected to each other and to said first and second levers respectively, means for locking said pair of levers against pivotal movement with respect to each other, and means for unlocking said locking means to permit pivotal movement of said pair of levers with respect to each other.
