Breaker Control Switches

Rotary Knife Switches

Application

Rotary cam Switches are modular in design with contact housing stacked with indexing mechanism. The operating knob is attached to steel shaft that rotates the cams which drive the contacts to an unlimited combinations of contact programs.
The housing is made of engineering thermoplastic material contents two sets of contacts. The contacts are mechanically opened & are closed using springs that provide force to achieve desirable contact pressure.
Two poles can be arranged in each set of contact housing making it compact for the application.

Features & Specification
