Rotary Auxiliary Wiping Contact Switches

Being a customer centric organization, we are involved in manufacturing, exporting and supplying a supreme quality range of Rotary Auxiliary Wiping Contact Switches in Nashik, Maharashtra, India.

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 equipment such as HV - Gas Circuit Breakers and various equipment 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 converted into rotational through links & levers.
