Allen-Bradley 800MS-XO24AS Small Square Push Button

Allen-Bradley 800MS-XO24AS is a 22.5 mm small-square push-button operator from Rockwell Automation’s 800MS family. The XO24 designation identifies a 24 V AC/DC illumination variant, and this gray-bezel version is designed for panel mounting in control enclosures where quick, visible operator input is needed. As a momentary push button, pressing the button produces a brief actuation event, and the unit is intended to be used with compatible 22.5 mm contact blocks to implement the electrical switching; these blocks are sold separately. In typical industrial control panels, this compact operator serves as a convenient start, stop, or reset input, with 24 V illumination aligned to common 24 V control circuits. When paired with a suitable 22.5 mm contact block, the 800MS-XO24AS can provide either normally open or normally closed operation, depending on the chosen configuration and insertion accessories.
