The PG SERIES is our Pointer Grip Series with side gripping surfaces. All these knobs come with side serrations for gripping. This style knob has been utilized for many different applications. It is used in general for rotary switches where torque may require a better grip. The serrations make it ideal when used as a "Pull-to-Turn" knob. This unit also serves as a control knob for Potentiometers and other rotary devices. All of our backlighted knobs can be manufactured for night vision use. Our knobs meet NVIS "Green A" requirements.
