Phase Selector Switches

Rotary Cam Switches

Application

Rotary Cam Switches are modular in design. They have contact housing stacked with indexing mechanism. The operating knob is attached to a steel shaft that rotates the cams which drives the contacts to an unlimited combinations of contact programs.
The housing is made of engineering thermoplastic material. It contains two sets of contacts. The contacts are mechanically opened. They close using springs which aid in providing required force to achieve desirable contact pressure.
Two poles can be arranged in each set of contact housing making it compact for the application.
