1M Linear 1/8W Potentiometer with Split Splined Shaft

This 1M linear taper potentiometer is a compact adjustable control for electronics repairs, audio projects, DIY circuits, and custom panels. The linear taper provides a smooth, even resistance change as the shaft is turned.

The solder lug terminals are easy to wire by hand, and the 6mm split splined shaft fits many standard push-on knobs. This makes it a convenient part for replacing worn controls or adding a new adjustable control to a project.

1M Linear Potentiometer for Electronics Projects

A 1M potentiometer is useful in circuits that need a high-value adjustable resistance or voltage control. It can be used in signal-level circuits, audio projects, test fixtures, repair work, and custom electronics builds.
