ActiveAR22 22mm Green Flush Push Button 1NO
Fuji Electric AR22 green push button — Japanese industrial standard.
Common Applications
The default push button in Japanese factories using Fuji drives and PLCs. AR22 is Fujis 22mm modular range — equivalent to Schneider XB4 and Eaton M22. Common on machine tools, food processing, and semiconductor equipment built in Japan. If the panel has a Fuji FRENIC drive, the buttons are likely AR22.

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.
