Rotary Auxiliary Wiping Contact Switches


Rotary Auxiliary Wiping contact switches are modular in design and are very versatile for switching a.c. as well as d.c. resistive & inductive loads. They are used as auxiliary contacts in equipments such as HV - Gas Circuit Breakers and various equipments where in it is linked mechanically to the equipment and follows the position as per the linkage. In most cases a straight motion of main contacts is conver ted into rotational through links & levers.

  • Wiping type of contacting making it suitable for switching d.c. loads.
  • Self cleaning of contacts is done during the operation.
  • Capable of carrying heavy currents.
  • Modular design to achieve any number of poles with minimum components.
