Rotary switches move in a circle and can stop in several positions.

Rotary coded dual in-line package (DIP) switches are activated by a rotating shaft and have several stop positions.

Pushwheel switches are rotary switches that operate using a rolling wheel.

DC motors are most commonly used in variable speed and torque applications.

Rotary position sensors include potentiometers, resolvers and a variety of magnetic and capacitive technologies.

Switches are devices that allow electric current to flow when closed and prevent current flow when opened.

Rotary positioning stages are devices with tables or shafts that may be rotated to any angular position.
