Emergency Stop Switches / E-Stop Switches 22mm Emergency-Stop Lighted
Research Notes
1. What this is
AYLW412620-S is an IDEC flush-silhouette LW-family device (AY/AV): 2mm-projection flush bezel, ø28 round / 28mm square — illuminated pushbutton or pilot light. Exact operator/contact config is not fully decodable from the code alone. This specific variant is Black.
2. Part-number decode
- Series: IDEC LW flush-silhouette — 25/28mm flush bezel illuminated-pushbutton/pilot
- Color: Black
3. Compatibility & ordering
Panel cutout: 25/28mm flush bezel. Unibody construction — the operator and contact are a single assembly. Cross-reference by size, operation, contact arrangement, and color to an equivalent from another IEC command-switch line (Schneider Harmony, Allen-Bradley 800F/800T, Siemens 3SU, Eaton M22) if IDEC is unavailable.
4. Data-quality note
The series is identified, but one or more code segments (exact operator/contact config) are not fully determinable from the part number alone — treat those as indicative and confirm against IDEC's datasheet for a critical order.

Paigalduse kiirjuhend
Panel cutout: 22mm. Mount with the yellow backing plate visible (required by EN/ISO 13850).
Wiring: Wire NC contacts in series with the safety relay input channels. Use dual-channel wiring for SIL 3 / PLe applications. Never wire directly to a motor contactor.
Testing: Press the e-stop and verify the machine stops within the required time. Test the reset mechanism. Repeat monthly per EN/ISO 13850.
Mõõtmed
Veaotsing
E-stop won't reset (twist/pull doesn't release)
Check for debris in the mechanism. For twist-release: turn clockwise 45-90 degrees. For push-pull: pull straight out firmly. If the mechanism is stuck, the internal latch may be damaged — replace the entire head assembly.
Machine doesn't stop when e-stop is pressed
Critical safety issue. Immediately lock out the machine. Check wiring — NC contacts must be in series with the safety relay. Verify the safety relay is functioning. A broken wire in an NC circuit should cause a stop, so check for a wiring bypass.
Safety relay faults after e-stop reset
The safety relay detects a cross-fault between the two monitoring channels. Check that both NC contacts on the e-stop are switching simultaneously. One contact may be welded closed — replace the contact block.
