The Allen-Bradley A3PLE1-6L5R-11 is an illuminated pushbutton with a two-position momentary actuator, a 120 V transformer for the integral lamp, a red lens, and a 1NO1NC contact block. It belongs to the A3P family of 22 mm panel-mount control devices used in industrial control stations, operator panels, and machine control pedestals.
The 120 V transformer inside the pushbutton powers the red LED or incandescent lamp directly from the control voltage — no external power supply needed for the illumination. The 1NO1NC contact block provides one normally-open and one normally-closed set, enough for a start/stop or enable/acknowledge pair in a single operator. Two-position momentary means the actuator returns to rest when released; it does not latch. This suits jog, inch, or test functions where the action must end when the operator lets go.
