ActivoHarmony XB4 Illuminated Green Push Button 24V LED
Illuminated green flush push button with integrated 24V LED for Schneider Harmony XB4 series. 22mm cutout, IP66 rated. Provides visual confirmation of active state.
Aplicaciones comunes
Illuminated green push button that lights up when the controlled equipment is running — the LED confirms at a glance that the motor, pump, or compressor is active. Found on commercial kitchen panels where the green glow tells the operator the fryer or oven has reached temperature, and on HVAC control panels indicating the fan or compressor is energized. The integrated 24V LED connects directly to PLC outputs or contactor auxiliary contacts. Pairs with the red illuminated ZB4-BW343 for a matched start/stop set with visual feedback. The IP66 metal bezel handles steam cleaning and humid environments without corrosion.

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.

Lo que dicen los usuarios
“For any panel with more than 3 buttons I always go illuminated. Operators can see at a glance which station is active. The extra $8-15 per button pays for itself in reduced mis-presses. Schneider XB4 illuminated are my go-to.”
“Always use illuminated for anything the operator needs to see status on. The LED confirms the circuit is active — especially important in noisy environments where you cant hear a relay click. Non-illuminated only for basic start/stop where a separate indicator exists.”
