Active22mm Green Flush Push Button 1NO
Allen-Bradley 800F series green flush momentary push button with 1NO contact block included.
Common Applications
The most common industrial push button in North American plants. Allen-Bradley 800F is the default choice for system integrators using Rockwell/AB PLCs. Found on every ControlLogix and CompactLogix panel in the US. The integrated contact block saves assembly time vs modular European designs.

Installation Quick Reference
Panel cutout: 22mm. Insert from the front of the panel, secure with mounting nut from behind (tighten to 2-3 Nm).
Contact block: Snap or screw the contact block onto the rear of the button body. Ensure the contact block orientation matches the wiring diagram — NO terminals are usually marked.
Wiring: Use 0.5-2.5mm² stranded wire with ferrules. Tighten screw terminals to 0.8 Nm. Test the button function before energizing the circuit.

Troubleshooting
Button doesn't respond when pressed
Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.
Works intermittently
Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.
Button feels mushy or doesn't click
The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.

What People Are Saying
“If you are a Rockwell shop, use 800F. If you are a Schneider shop, use XB4. Both are excellent. The 800F is slightly more expensive but integrates perfectly with AB panel accessories. In North America, 800F is the default — your electricians already know how to wire them.”
