Rotary Auxiliary Cam Switch


Rotary auxiliary cam switches are modular in design are very versatile for switching a.c as well as low voltage d.c. resistive & inductive loads. They are used as auxiliary contacts in equipments such as MV & HV – Vacum Circuit Breakers, Gas Circuit Breakers, Isolators and various equipments wherein it is linked mechanically to equipment and follows the position as per linage. In most cases a straight motion of main contacts is converted into rotational through links & levers. These switches offer advantages of having unlimited combinations of switching angles and indexing angles.



  • Cams used for contacting makes it suitable for switching in various programmable combinations.
  • Silver alloy contacts used has a very high durability & endurance.
  • A double break contact ensures positive making & breaking.
  • Modular design to achieve any number of poles with minimum componenents.
  • Superior insulating material ensures electrical & mechanical stability.
