The Allen-Bradley 800MR-PT16A is a 22.5 mm round pilot-light push-button with an amber lens, designed for mounting in standard 22.5 mm operator cutouts. It uses a transformer-type pilot light (PTT) with push-to-test and is powered from 110–120 V AC at 50/60 Hz, featuring an incandescent lamp and stab-terminal connections. This variant ships without a separate contact cartridge.
