M22-DP-G-K10
ActiveM22 Green Flush Push Button with 1NO Contact Block
Green flush momentary push button for Eaton M22 series with integrated 1NO contact block. 22.5mm cutout, IP67 front. Ready-to-install complete unit.
Common Applications
Pre-assembled green push button with an integrated 1NO contact block — saves installation time compared to buying the head and contact separately. This is the same M22-D-G button with a K10 contact block factory-mounted, ready to wire. Popular with maintenance teams doing quick replacements on food processing and packaging lines where minimizing downtime matters more than component flexibility. The integrated assembly also reduces the chance of a loose contact block causing intermittent faults. Cross-references to the Schneider ZB4-BA3 + ZB4-BZ101 combination or the ABB MP1-10G.
Research Notes
1. Overview
The Eaton M22-DP-G-K10 is a pre-assembled "complete device" from Eaton's RMQ-Titan M22 modular pilot device series, combining the M22-DP-G green mushroom-head actuator with an M22-K10 1NO contact block. It is a 22.5mm panel-mount, spring-return (momentary) pushbutton, identified by catalog number 216716 for the actuator head component. The RMQ-Titan M22 line is Eaton's flagship 22mm pushbutton platform, manufactured in Germany/Morocco, widely stocked by global distributors and directly competing with Schneider Electric's Harmony XB4 series (ZB4-BA3 + ZB4-BZ101), ABB MP1-10G, and IDEC HW1B-M110G.
2. User Sentiment
No forum or community reviews were found specifically for this combination part number. However, Eaton markets the RMQ-Titan M22 line explicitly as "the best solution for machine and panel builders," and the series is widely stocked across global distributors, indicating strong industrial acceptance. The modular snap-fit system is praised for allowing easy single-person installation even when the front and back of the panel are not simultaneously accessible — a noted ergonomic advantage over competitors. No known complaints were found in the fetched sources; the line's 5,000,000-cycle mechanical life is a consistent selling point.
3. Real-World Applications
The green mushroom head format (36.5mm cap) is the standard choice for Start, Run, and Auto machine control buttons in industrial panels, conveyor systems, and process automation equipment. The IP67/IP69K rating makes it suitable for food processing, washdown environments, and outdoor enclosures. The M22 series is used by machine builders and OEMs across manufacturing, packaging, and material handling. Peruvian distributor Lepsac lists it alongside emergency-stop and stop-button variants (M22-DRH-R/K01, M22-DP-R/K01), confirming its role in complete machine control panels.

5. Ordering & Compatibility
The M22-DP-G-K10 is the complete device (actuator + contact block bundled). The actuator head M22-DP-G (catalog 216716) is also sold separately. The contact block M22-K10 is sold separately at DigiKey (~$15.64/each, ~$9.61 at 1,000 qty). The complete device is priced at $2.21–$5.02 at volume per The Button Index aggregation; M22-DP-G actuator alone is ~$14.92 (kentstore) / £10.04 (UK). Alternate catalog number M22-DP-GQ exists. Up to 6 contact blocks can be stacked per operator; NC version is M22-K01. Maintained (latching) mushroom version is M22-DRP-G. Compatible with M22-A mounting adapter. Related part numbers in the same panel assembly: M22-DP-R/K01 (red, 1NC stop button), M22-DRH-R/K01 (red extended/emergency stop).
6. Known Issues
No significant issues reported in fetched sources. The actuator head is sold separately from the contact block in many distributor listings, which can cause confusion when ordering — buyers must confirm whether they are purchasing the complete device (M22-DP-G-K10) or just the actuator (M22-DP-G, catalog 216716) or just the contact block (M22-K10). Distrelec explicitly notes "Order fastening adapter and contact elements separately" for the actuator-only listing, confirming this is a common source of ordering errors.

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.

Wiring Diagram
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.
