The Casambi Push Button Interface 4CH 24Vdc for installation behind a push button by Casambi is a compact control module that allows up to four push buttons to be connected to a wireless Casambi lighting system, enabling functions such as switching, dimming, scenes and group control to be configured via Bluetooth and the Casambi app without additional control wiring, making it ideal for renovation and new build projects where discreet integration behind existing switches is required and a 24Vdc power supply ensures stable operation.
