M22-DL-W

1. Overview

The Eaton M22-DL-W (Eaton catalog no. 216922) is the illuminated flush pushbutton actuator in Eaton's RMQ-Titan M22 22.5mm modular pilot-device family (the Moeller heritage brand behind M22). Eaton's own catalog literally titles the part "Eaton M22 modular pushbutton" and its own datasheet calls it an "Illuminated pushbutton actuator" with Product Sub Type "None" — it is the white, unlabeled (blank), spring-return front element only, with a titanium/chrome-colored bezel and front ring. It belongs to the same actuator family as M22-DL-R/G/Y/B (red/green/yellow/blue) and M22-DL-X (no lens insert).

2. User Sentiment

Dedicated end-user reviews are scarce — this is a B2B industrial control component, not a consumer product, and no forum threads or star-rated reviews with substantive commentary were found on Amazon.com/.de or elsewhere. Distributor copy consistently praises the M22/RMQ-Titan line's "space-saving construction that enables fast assembly" (Newark, Galco) and "attractive design and practical handling" (Farnell/RS). The recurring theme across independent distributors (DigiKey, TME, ilecsys.co.uk, edwardes.co.uk, elfetex.cz) is a practical complaint-in-disguise: buyers repeatedly need reminding that the bare M22-DL-W ships as a "Pushbutton Head Only" — several listings explicitly flag "Contact Block and LED module required for operation" to head off confusion.

3. Real-World Applications

Used across industrial control panels, switchgear cabinets, and machine HMI/pilot-device panels wherever a 22.5mm illuminated momentary pushbutton is needed — general machine start/stop stations, panel-builder custom control desks, and SmartWire-DT (SWD-RMQ) wired control panels. Eaton markets the M22 family broadly for "machine and panel builders" (cca.co.uk) and it appears throughout European and North American industrial distribution (Rexel, TME, RS, Farnell, Grainger, Radwell) as well as OEM equipment (e.g., referenced on agricultural/turf equipment control panels).

4. Technical Specifications

(Per Eaton's own datasheet for 216922/M22-DL-W)

• Type: Illuminated pushbutton actuator (RMQ-Titan, M22 series) — front element/head only, no integral contacts
• Color: White button ("Colour button: White"); bezel/front ring: chrome/titanium, plastic
• Design: Flush ("Classical"), flat button, momentary/spring-return, blank (no inscription)
• Panel cutout: 22.5mm round; front dimensions 22×22mm; overall ~29.7mm head, 30×30×30mm envelope; weight 0.01kg
• Degree of protection: IP66, IP67, IP69K, NEMA 4X/3R/12/13 overall; front side specifically IP67/IP69K + NEMA 4X
• Mechanical life: 5,000,000 operations; actuating force 5N; operating temp -25°C to +70°C
• Certifications: UL 508, CSA C22.2 No. 14-05 / 94-91, IEC/EN 60947-5, CE, VDE 0660
• Connectivity: SmartWire-DT compatible via SWD-RMQ connection
• Contact block: none integral — rated current, heat dissipation all listed as 0A/0W in the official datasheet; requires separate M22-K-series contact block (e.g., M22-K10 = 1NO, M22-K01 = 1NC, M22-K11 = 1NO+1NC)
• Illumination source: none integral — actuator is only "suitable for illumination"; requires a separate LED element (M22-LED-W ≈12-30V AC/DC, or M22-LED230-W ≈230V AC) which plugs in behind the actuator

5. Ordering & Compatibility

Street pricing for the bare actuator runs roughly $17.54 (DigiKey, qty 1) down to ~$11.76 (500+), or about £7.95–£13.63 at UK distributors (ilecsys, cca.co.uk, gkcontrols) and €18 at German distributors (Jacob.de). By contrast, "complete device" SKUs that bundle the actuator with a contact block and LED — e.g. M22-DL-W-K10-W (1NO, integrated LED, ~$74-$82 at DigiKey) or M22-DL-W-K20-W (DPST-NO, 6A@240VAC/3A@24VDC contacts, 12-30VAC/DC LED, ~$82.38) — cost roughly 4-5× more, reflecting the added components. Several distributors (Automation24 UK/DE) sell explicit "Set" bundles named e.g. "M22-DL-W/-A/-LED230-W/-K10," spelling out that a complete illuminated switch requires four separate Eaton part numbers: the actuator (M22-DL-W), a mounting adapter (M22-A), an LED element (M22-LED-W or -LED230-W), and a contact block (M22-K01/K10/K11/K20). A related variant, M22-DL-W-X1 (Eaton no. 216942), is the same bare actuator with a different inscription/circuit code — it also explicitly "Requires Contact Block(s), Illumination Source" per DigiKey.

6. Known Issues

No safety recalls, failure patterns, or significant technical complaints were found. The main recurring "issue" in the sourced material isn't a defect but a buying-confusion point: multiple independent distributors (DigiKey, TME, ilecsys.co.uk, edwardes.co.uk, elfetex.cz) felt it necessary to explicitly warn buyers that the bare M22-DL-W does not include a contact block or LED lamp — implying this is a common ordering mistake for people expecting a ready-to-wire switch.
