RMQ M22 Green Flush Push Button

Moeller RMQ M22 Series Introduced circa 2000

Moeller RMQ-Titan M22 green push button — pre-Eaton branding.

Common Applications

Same button as the Eaton M22-D-G — just the old Moeller branding. If the machine was built in Germany/Austria/Czech Republic between 2000-2008, you will see Moeller on the panel door. Eaton part numbers cross-reference directly. No functional difference.

Compatibility

Identical to Eaton M22-D-G. Eaton acquired Moeller in 2008. All Moeller M22 parts are directly interchangeable with Eaton M22 parts. Same contact blocks, same mounting, same accessories. Just different branding on the button head.

Installation Quick Reference

Panel cutout: 22.5mm. 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.
