Norton 503 Vestibule Switch — Hard-Wired, 1-1/2 in x 4-3/4 in, Finish 32D

The Norton 503 Vestibule Switch is a hard-wired, single-door wall-mounted push switch designed for use with low-energy automatic door operators in commercial vestibule applications. Featuring a compact 1-1/2 in x 4-3/4 in face plate in a satin stainless finish (32D) with blue lettering, the 503 integrates cleanly into lobbies, corridors, and building entrances where an accessible activation point is required. It is UL Listed and rated at 15 amp at 125 VAC, providing reliable performance in demanding commercial environments.

Note: The Norton 503 is a single-door vestibule switch. If two-door vestibule control is needed, see the Norton 504 instead. An optional 559 back box is available for flush mounting in standard wall frames; the switch fits a 1-3/4 in frame.

Key Features & Benefits

• UL Listed: Independently certified for use in commercial installations where code compliance and inspection sign-off matter.
• Momentary SPDT Contact: One momentary single-pole double-throw contact provides a clean, low-latency activation signal to compatible door operator controls.
• 15 A / 125 VAC Rating: Sufficient capacity for hard-wired integration with low-energy operator control circuits.
• Compact 1-1/2 in x 4-3/4 in Face Plate: Slim profile fits standard commercial wall locations without requiring oversized cutouts.
• 32D Satin Stainless Finish with Blue Lettering: Professional appearance consistent with commercial architectural hardware finishes; legible blue text aids user recognition in vestibule environments.
• Optional 559 Back Box: Enables clean flush installation in new construction or renovation; ordered separately.
• Single-Door Application: Purpose-built for activating one door operator — distinct from the 504, which controls two doors in a vestibule sequence.

Applications

• Accessible building entrances requiring wall-mounted operator activation
• Commercial vestibules, lobbies, and corridor doors paired with low-energy swing or slide operators
• ADA-accessible door operator installations where a separate push switch is specified
• Renovation or new construction projects requiring hard-wired operator control switches
