M22-D-W

1. Overview

The Eaton M22-D-W is a non-illuminated, flush-style pushbutton actuator from the RMQ-Titan M22 series, part of the Moeller product family now under Eaton. It is an actuator-only component — a white, flat-faced operator button with a titanium/silver-colored plastic bezel designed for a 22.5mm panel cutout. The "D" suffix designates flush/flat actuator style, and "W" designates white color. Eaton catalog number is 216592, with alternate code M22DW. The M22 platform is a globally distributed modular control device family widely used in industrial machinery and automation panels.

2. User Sentiment

No forum or community review-style sentiment data was found in the research findings. Distributor product descriptions uniformly describe the M22-D-W as a reliable industrial actuator. The Emas.cz Czech retailer notes it offers "good value for money from a proven manufacturer." The RMQ-Titan family is broadly marketed on ergonomics: "ergonomically shaped button elements adapted to fingertip contours for comfortable operation." No known reliability complaints or recalls were found across the 699 research sources.

3. Real-World Applications

The M22-D-W is used primarily in industrial machine control panels, automation control cabinets, and equipment requiring a white momentary momentary operator. Onninen Poland describes it as suitable for "control panels, machines, and industrial equipment." The spring-return design makes it appropriate for safety-relevant applications where it is important that the device does not remain active after operator release. Its IP67/IP69K rating makes it suitable for wash-down environments, food processing, outdoor installations, and other harsh-duty applications.

5. Ordering & Compatibility

Pricing varies by channel: ~$7.10–$12.50 USD single-unit in the US; ~€5.73–€10.12 in Europe; ~CZK 120–131 in Czech Republic. DigiKey (PN 5730-M22-D-W-ND) offers volume pricing down to $7.68/unit at 1,000 pieces. The M22-D-W is an actuator only and requires a separate contact block to form a functional switch. Compatible front-mount contact blocks: M22-K10 (1 NO), M22-K01 (1 NC), M22-K11 (1 NO + 1 NC), M22-K20 (2 NO), M22-K02 (2 NC), M22-K21, M22-K12 — up to 6 contact elements across 2 levels. The M22-D-W+M22-A bundle (RS 78635765, Farnell DP 3717148) includes an M22-A mounting bracket. Complete ready-to-use device variant: M22-D-W-K10-BVP (catalog 132619, blister pack with 1 NO contact block). Alternate codes: M22DW, Vendor ID 3-5485-001A (CMAFH), Cutler-Hammer branding (US).

6. Known Issues

No significant issues reported across sourced findings. The only consistent caveat is that the M22-D-W is an actuator-only component that ships without contact blocks — users who inadvertently order only the M22-D-W without contact blocks will receive a non-functional switch body. Eaton provides the M22-D-W-K10-BVP blister pack as a complete-device solution for those needing a ready-to-use unit. Some eBay listings are sold "new, no box" by secondary market suppliers (Mara Industrial, Radwell), but products appear genuine.
