安装快速参考

Mounting: Snap onto the rear of any compatible button body in the same series. The latch clicks audibly when properly seated. Some models require a mounting adapter.

Wiring: Terminals are marked NO (11/12) or NC (21/22). Use 0.5-2.5mm² wire with ferrules. Tighten to 0.8 Nm. Verify with a multimeter before energizing.

故障排除

Intermittent switching

Silver contacts are pitted from arcing. Replace the contact block — they are consumable parts. If arcing is severe, check that the switched load doesn't exceed the contact rating (typically 6A at 120VAC).

Contact block won't snap onto button body

Verify the contact block series matches the button head series (e.g., Schneider ZB4 blocks fit ZB4 heads only, not ZB5). Check for debris or damage on the mounting tabs.
