Working Mechanism

  • These switching devices consist of a coil that generates a magnetic field when current flows through it.
  • The magnetic field helps to attract the armature that eventually closes the contacts to complete the electrical circuit.
  • As the current flow stops, the magnetic field decreases, causing the armature to return to its original position.
  • This causes the contacts to open again and break the circuit.

Frequently Asked Questions

What is a purpose of a flag indicator?

Flag indicators consist of a flag or a marker attached to the shaft or a pole to provide a clear and visible indication of the relay, such as whether it is energised (activated) or de-energised (deactivated).

How to remove the coil in general-purpose relays?

  • Ensure the power to the control panel is disconnected.
  • Remove the cover of the panel or simply unplug the relay from the socket.
  • Once the relay is removed, locate the coil. It is normally located at the bottom of the relay and is cylindrical or rectangular in shape.
  • Carefully disconnect the wires from the relay by either releasing the clips that hold them securely or simply pulling them out.
  • Remove the old coil and replace it with a new one of the same specification.
