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.

Electric rotary actuators drive components rotationally via electromagnetic power.

Absolute rotary encoders use optical, mechanical, or magnetic indexing for angular measurement.

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

Tilt sensors, switches and inclinometers generate an artificial horizon and measure angular tilt with respect to this horizon.

Air cylinders are pneumatic linear actuators that are driven by a pressure differential in the cylinder's chambers.
