£113.31
The Carlo Gavazzi B5B-LS4-U is a 55 × 55 mm smart-house light switch designed for building automation and intelligent lighting-control applications. Supplied with a dark frame, this compact wall-mounted control provides a clean user interface for operating lighting and other functions assigned through a compatible Carlo Gavazzi smart-house system.
The B5B-LS4-U belongs to Carlo Gavazzi's configurable light-switch family and is represented by the B5X-LS4-U device within the Carlo Gavazzi Sx configuration environment. Its four-button interface supports configurable input actions, allowing different functions to be associated with short, long and very-long button activations according to the automation project.
Designed for integrated building control rather than conventional stand-alone mains switching, the B5B-LS4-U provides a flexible operator interface for smart lighting installations. Configurable activation timings allow each push-button to perform different commands, making the unit suitable for residential, commercial and other automated-building applications requiring convenient multi-function wall control.
The Carlo Gavazzi B5B-LS4-U provides more functionality than a basic mechanical light switch by allowing its push-buttons to be configured as inputs within a smart-house automation system. Short, long and very-long activations can be interpreted differently by the controller, enabling multiple building-control commands to be accessed from the same compact wall interface.
Within the Sx Tool, the B5B-LS4-U is configured using the B5X-LS4-U light-switch profile. Long activation can be set between 1 and 5 seconds, while very-long activation can be configured between 0.5 and 15 seconds. This flexibility allows the switch behaviour to be tailored to the requirements of the individual room, lighting zone or building-automation project.

The B5B-LS4-U is a 55 × 55 mm four-button smart-house light switch designed as a configurable user interface for Carlo Gavazzi building-automation systems.
The B5B-LS4-U is part of Carlo Gavazzi's LS4 four-button light-switch family, allowing multiple control functions to be configured within a smart-house installation.
Yes. The system supports short, long and very-long activations. Long activation can be configured from 1 to 5 seconds, while very-long activation can be configured from 0.5 to 15 seconds.
The B5B-LS4-U is configured using the B5X-LS4-U device profile within the Carlo Gavazzi Sx Tool light-switch family.
The B5B-LS4-U is listed as a discontinued legacy Carlo Gavazzi product. It may therefore be particularly relevant for maintenance, replacement and expansion of existing compatible smart-house installations.
Carlo Gavazzi smart-house control devices provide configurable user interfaces for intelligent building automation, enabling lighting and other assigned functions to be controlled through integrated wall-mounted devices such as the B5B-LS4-U.
