Tactile Switches Illuminated Yellow LED and Cap
Research Notes
1. What this is
B3W-9000-Y1Y is an Omron B3 tactile switch.
2. Part-number decode
- Series: Omron B3
- Type: tactile switch
3. Compatibility & ordering
Omron makes industrial command switches (A22 22mm, A16 16mm — unitized, contact in the model code), illuminated pushbuttons/pilot lights (A3, M2), and a widely-used B3 PCB tactile-switch family. Match by size, function (pushbutton/selector/indicator/E-stop), colour, illumination, and contact arrangement, then use the Omron datasheet to confirm the exact colour and voltage encoded in the part number.
4. Data-quality note
The Omron series and switch type are decoded from the part number (grounded in the omron.com catalog and DigiKey listings; A22 corroborated by curated-loop work). Omron 22/16mm command switches are unitized — the contact arrangement is part of the model code — but the exact colour and voltage suffix should be confirmed against the Omron datasheet for a precise order (not guessed here).

Referencia rápida de instalación
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.

Solución de problemas
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.
