Contactor

The contactor is an electrical or electronic switch specially designed for high levels of electrical power. It has two switching positions and typically operates in the monostable mode. Contactors differ from relays in three major respects.

Differences to relays:

  • Relays are only designed for lower and contactors for higher switching capacities.
  • Relays have single-break contacts whereas contactors have double-break contacts.
  • Relays have hinged (clapper-type) armatures while contactors have plunger-type armatures to exert greater mechanical force to switch the larger contacts required for the higher switching capacity.
