Emergency Stop Switches / E-Stop Switches
Research Notes
1. What this is
EUS-44-712.001 is a EAO EUS emergency stop.
2. Part-number decode
- Series: EAO EUS
- Type: emergency-stop
3. Compatibility & ordering
EAO (Switzerland) makes premium modular HMI command switches — pushbuttons, indicators, selectors, and E-stops in numbered series (04/14/45/51/56/61/82/84). Match by type, actuation, illumination, sealing, and mounting, then use the manufacturer datasheet to confirm the exact contact and termination encoded in the part number.
4. Data-quality note
The EAO product line/type is identified; the detailed configuration is left to the datasheet rather than guessed. Flagged decoded-partial.

Référence rapide d'installation
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.

Dépannage
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.
