Definitions

  • the favorable action of the anvil can be explained by the absence of rebounding of the contacts during closing and therefore of a shock between the contacts which is more effective in crushing the contact surfaces.
  • the mass of the moving element is large enough to strike the moving contact strongly against the fixed contact and thus ensure a crushing of the contact surface and a low contact resistance.
  • the same result is obtained according to the present invention for a low mass contact bridge by attaching an anvil to the fixed contact.
