Definitions

  • Relays of this type are known ( US 4,703,293 . US 6,107,903 ). These relays include a solenoid system having at least one coil, a coil core, and two pole pieces defining two opposing relay sides.
  • the relay housing has fixed contacts of the switches on the opposite relay sides.
  • the movable contacts of the switches sit at the end of contact springs and are supported by an isolation platform, which is part of a movable block to which the anchor belongs.
  • Each of the contact springs leads to a center terminal, which are each electrically connected to pins.
  • the insulation gap between the respective contact spring and armature or pole piece is not very long, so that the known relay do not show good insulation properties.
  • the relay housing may have an insulating stationary arranged hood, the the first relay side covers the armature and the electromagnetic system and protects them against leakage currents through air and along surfaces.
  • a hood forms a very long distance for leakage currents, so that such leakage currents are largely suppressed.
  • a second switch For purposes of monitoring the armature position, a second switch may be provided which has a second armature spring with bridge contact and is arranged on the second relay side to cooperate with two fixed contacts arranged side by side there.
  • the load switch 20 can be designed for higher voltages and / or higher currents. For this purpose, a greater distance between the two fixed contacts 21, 22 is selected, whereby the two contact bodies of the movable contact 23 move apart and the sparking between the two fixed contacts 21, 22 is difficult.
