﻿As the name suggests, the rotary encoder is an operating device that transmits absolute or relative values by means of a rotary motion. For example, the brightness of a light can be increased by turning it clockwise and reduced by turning it anti-clockwise.
Rotary encoders can have end stops or support endless rotation as incremental encoders. Most rotary encoders also have an integrated press function, providing an additional operating option.

When operating the slide encoder, a sliding motion occurs in a horizontal or vertical direction. Slide encoders are generally designed as absolute encoders because the setting range is between two end values. The slide encoder can also have a push function that can be used for switching.
