Rotary Auxiliary Knife Switch

Application : Rotary auxiliary knife switches popularly known as wafer switches due to their modular & companct design are very versatile for switching a.s. as well as d.c. resistive & iductive loads. They are used as auxiliary contacts in equipments such as MV & HV - Vacuum Circuit Breakers, Gas Circuit Breakers, Isolators & Various equipments, where 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 converted into rotational through links & levers to operate the switches.

Features :

• Knife type of contacting making it suitable for switching d.c. loads.
• Self cleaning of contacts is done during the operation.
• Modular design to achieve any number of poles with minimum components.
• Brass inserts used in threads to endure more than required torque while mounting.
• Superior insulating material ensures electrical & mechanical stability.
