Why Choose the Carlo Gavazzi BEW-LS4-U ELKO 4-Channel Light Switch?
The Carlo Gavazzi BEW-LS4-U is a 4-channel programmable light switch designed for Carlo Gavazzi smart-house and Smart Dupline building automation applications. Developed specifically for installation with ELKO wall boxes and frames, this white wall-mounted control provides four individually programmable push buttons for convenient local control of lighting, roller blinds and other functions supported by the smart-house controller.
Each of the four push-button inputs can be individually programmed, allowing the BEW-LS4-U to perform different building automation commands according to the requirements of the installation. Four individually programmable blue LEDs provide visual status feedback, helping users identify the state of controlled functions directly from the wall switch.
The BEW-LS4-U is powered directly from the smart-house bus at 8.2 V nominal, eliminating the need for a separate local power supply. Its compact 55 × 55 switch format is designed for ELKO mounting systems, while configuration through the Carlo Gavazzi smart-house programming environment enables the switch to form part of a flexible and integrated building automation installation.

Flexible Control for Smart Buildings
Programmable wall switches provide a convenient interface between occupants and a building automation system. Rather than restricting each button to a conventional lighting circuit, the BEW-LS4-U allows its four push buttons to be assigned to functions supported by the Carlo Gavazzi smart-house controller, providing greater flexibility when configuring automated rooms and buildings.
The four programmable LED outputs provide visual feedback from the automation system, while bus-powered operation simplifies wiring by removing the requirement for a separate power supply at the switch. This makes the BEW-LS4-U suitable for coordinated control of lighting, blinds and other automated building functions from a compact ELKO wall-mounted interface.
Typical Applications
- Residential smart-home lighting control.
- Commercial building automation.
- Programmable room lighting control.
- Roller blind and shutter operation.
- Scene and function activation.
- Offices, meeting rooms and communal areas.
- Carlo Gavazzi smart-house installations.
- Smart Dupline building control systems using ELKO wall fittings.
