AttivoBACO 22mm Green Flush Push Button 1NO
BACO L21 22mm green push button — German value alternative.
Applicazioni Comuni
BACO is the European budget industrial button brand. Same 22mm mounting standard as Schneider/Eaton. Lower cost, acceptable quality for indoor panels. Popular with German machine builders who want to save on operator interface without compromising on mounting compatibility.
Compatibilità
Standard 22mm panel cutout. BACO contact blocks are proprietary — not cross-compatible with Schneider ZB4 or Eaton M22 contact blocks. However, the panel cutout is the same so you can replace the entire assembly with any 22mm brand.

Guida Rapida all'Installazione
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.

Risoluzione dei Problemi
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.
