Allen-Bradley 800MB-JX2BLA Push Button With Pilot Light

Allen-Bradley 800MB-JX2BLA Push Button With Pilot Light is a compact industrial control device that integrates a push-button actuator with an internal pilot light, delivering both manual actuation and visual status indication in a single unit. The model number 800MB-JX2BLA identifies this exact configuration within Allen-Bradley’s line of push-buttons, and the listing notes the designation (BK YL) alongside the part number. This configuration supports on-panel operation where an operator can initiate a function while the built-in light provides a visible signal of circuit status. By combining actuation and indication in one body, the device can simplify panel layouts by reducing the need for a separate indicator lamp and associated wiring. This type of component is commonly used in control panels and machine automation setups to provide immediate, local feedback about the state of a circuit or function, aiding operators in quickly assessing system status and readiness for the next action.
