В производстве22mm Yellow Extended Pushbutton Actuator (M22)
Eaton M22 extended yellow push button.
Типичные применения
Extended yellow for jog/intervention functions where raised access is needed.
Research Notes
1. Overview
The M22-DH-Y is an Eaton (Moeller) RMQ-Titan M22 modular pushbutton actuator/operator: 22.5 mm, extended (raised) button, momentary (off→on) action, non-illuminated, yellow button with silver metal bezel. It is the yellow member of the M22-DH extended family (cf M22-DH-R red, M22-DH-G green). As with the whole M22 line it is a front element only — the contact block and mounting adapter are ordered separately, so this SKU carries no integral switching. The plastic-bezel variant is M22S-DH-Y; complete devices add a contact (e.g. M22-DH-Y-K10 = +1 NO).
2. User Sentiment
Little consumer sentiment as an industrial part, but the M22 platform is well regarded for build quality and its tool-free clip-in contact system. Yellow is conventionally used for "attention/abnormal condition" or reset per IEC 60204/60073 color coding, and the extended head suits gloved or high-visibility operation — at a slightly higher accidental-press risk than the flush M22-D.
3. Real-World Applications
Machine control panels and control stations where a raised yellow button signals a caution/reset/abnormal-condition function; OEM equipment needing high-visibility momentary control. (A raised yellow momentary is a control button, not an E-stop.)
4. Technical Specifications
- Type: M22 extended (raised) momentary pushbutton actuator (front element only)
- Color / bezel: Yellow button, silver (chrome) metal bezel (M22S-DH-Y = plastic bezel)
- Size: 22.5 mm cutout
- Contact: none integral — add M22 contact blocks (M22-K10=1NO, M22-K01=1NC, M22-K11=1NO+1NC, M22-K20=2NO)
- Sealing: IP67 / IP69K at the front; NEMA 4X / 13
- Mechanical life: ~5,000,000 operations
- Approvals: UL, CSA, CE (per built-up device)
5. Ordering & Compatibility
Order the actuator plus a contact block + fixing adapter, or a pre-bundled complete device. Fits standard 22.5 mm cutouts and is interchangeable within the M22 ecosystem (holders, legend rings, guards). Stocked by Eaton, Amazon, Platt, and general electrical distributors.
6. Known Issues
No notable reliability issues; a mature modular design. The usual pitfall is modular: a bare M22-DH-Y actuator does nothing until a contact block is added.

Краткое руководство по монтажу
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.

Устранение неисправностей
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.
