The Smart Laffey D8C Series is an adaptable plastic tact switch featuring modular, detachable button keycaps designed for smart hotels, residential automation, and commercial buildings. Engineered for flexible key customization and effortless maintenance, it delivers silent tactile feedback and native support for KNX, Zigbee, Matter, RS485, and Tuya automation systems.
The Smart Laffey D8C Series offers maximum versatility for hospitality and smart building installations. Built with a unique detachable button structure, keycaps can be easily swapped or customized with laser-etched text and service icons without removing the wall-mounted switch chassis. This makes it ideal for hotel guest rooms where scene labels, room services, or language choices need updating.
Underneath its modular surface, the D8C integrates a silent TPE rebound mechanism that eliminates harsh mechanical clicking sounds. The panel operates across low-voltage bus systems (12V/24V) as well as mains voltage installations (220V), conforming to standard UK and EU electrical box mounting standards.
