PB411 Access Button — Metal, Narrow, SpringLoaded, Surface Mount, NO/COM A compact, durable access button designed for reliable door and gate control where space is limited. The PB411 provides a narrow profile, solid metal construction, and springloaded action for consistent, repeatable operation. Its NO/COM contacts make wiring straightforward for most access control systems. Key benefits Spacesaving design: narrow profile fits tight frames, slim panels, and compact housings where standard buttons will not. Built to last: metal housing resists deformation from repeated use and maintains alignment over time. Positive tactile action: springloaded mechanism returns the button to flush position after each press for predictable operation. Simple wiring: Normally Open and Common terminals allow direct connection to electric strikes, mag locks, intercoms, and access control panels. Easy surface mounting: installs on walls, door frames, or panels without special recessing. What this button solves Eliminates fit issues when replacing bulky pushbuttons on slim door frames. Reduces mispresses and false activations thanks to a defined spring . Provides a robust control point that integrates with standard access systems using NO/COM wiring. Important attributes Function: momentary pushbutton with spring . Contacts: Normally Open and Common configuration. Mounting: surface mount for quick installation on flat surfaces. Material: metal housing for durability. Profile: narrow form factor for constrained spaces. Typical applications Office entry release: surface mount next to interior doors to trigger electric strikes or magnetic locks. Gate or pedestrian access: install on gate posts or control panels where a slim, weatherresistant button is required. Intercom or entry panel upgrade: worn or oversized buttons on intercom housings while keeping existing wiring. Installation notes Connect to the NO and COM terminals on the access control circuit. Surface mounting requires a flat area on the door frame, wall, or panel. Use appropriate screws for the mounting surface. The PB411 is a practical choice when you need a reliable, compact, and durable access pushbutton that integrates with standard NO/COM access systems.
