Research Notes
1. What this is
Q18DR-SW is an Eaton device — series not recognized.
2. Part-number decode
- Series: Eaton (series not recognized)
3. Compatibility & ordering
Eaton's M22 (RMQ-Titan, 22mm) and E30 / 10250T (30.5mm heavy-duty) are its principal command-switch ranges. This is a complete/integrated device. Match by size (22 / 30.5mm), function (pushbutton/selector/indicator/E-stop), color, illumination, and contact arrangement; cross-reference to Schneider Harmony, Allen-Bradley 800F/800T, Siemens 3SU, or IDEC HW by the same attributes if needed.
4. Data-quality note
The exact Eaton series/configuration could not be confidently decoded from this part number. Kept and documented; flagged needs-verification.

Hızlı Montaj Kılavuzu
Panel cutout: 22mm. 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.
Boyutlar
Sorun Giderme
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.
