Emergency Stop Switches / E-Stop Switches
Research Notes
1. What this is
1.15105.0210000 is a RAFI RAFIX/LUMOTAST command switch.
2. Part-number decode
- Series: RAFI RAFIX 16/LUMOTAST
- Type: command switch
- Panel cutout: 16/22mm
3. Compatibility & ordering
RAFI (Germany) makes RAFIX/LUMOTAST modular HMI command switches and MICON short-stroke PCB keys. 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 RAFI series and switch type are decoded from the part number (grounded in the manufacturer catalog and distributor listings). The exact contact arrangement, termination, and cap/colour are encoded in the full order code — confirm against the datasheet for a precise order (not guessed here).

Installationskurzanleitung
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.

Fehlerbehebung
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.
