Theben LUXORliving T4.1 Push-Button Interface, 4-Channel, Flush-Mounted 4800405

The LUXORliving T4.1 from Theben converts conventional push-buttons or potential-free contacts into KNX-compatible inputs for the LUXORliving smart home system. Unlike a standalone actuator, it mounts directly behind standard switches in a flush-mounted box, preserving the existing room aesthetic while adding four independent control channels.

Highlights

• Four potential-free inputs for switches, push-buttons, or contacts
• Each input configurable for switching, dimming, blinds, scenes, or value transmission
• Powered directly from the LUXORliving bus – no separate power supply needed
• Compact design with screwless plug-in terminals for quick installation
• Compatible with standard flush-mounted boxes and common switch ranges

In daily use

Install the T4.1 behind a standard switch or push-button, connect the existing wiring to the screwless terminals, and connect the two-wire LUXORliving bus. Using the LUXORliving IP-Router or ETS software, assign each input a function: toggle a light, dim a lamp, move blinds, recall a scene, or send a value. The device remains completely hidden, so the room's design stays unchanged.
