MERTEN KNX Push-button Interface 4-gang MTN6002-0004S

The MERTEN KNX Push-button Interface 4-gang MTN6002-0004S converts four potential-free contacts into KNX telegrams, enabling standard switches or push-buttons to control KNX functions. Unlike standalone KNX push-buttons, this flush-mounted interface integrates conventional wiring into the bus system without replacing existing switch plates.

Highlights

• 4 independent inputs for potential-free contacts
• Flush-mounted installation in standard switch boxes
• Powered directly from the KNX bus (24 V DC)
• Configurable via ETS for switching, dimming, blinds, and scene control
• Supports logic functions, counters, and sequences per channel

In daily use

Each input can trigger switching, dimming, blind control, or value transmission. Scene control (1-bit/8-bit) and advanced functions like counters and logic operations allow flexible automation. The compact design fits behind existing push-buttons, preserving room aesthetics while adding KNX connectivity.
