Executive Metal Aesthetics with Modular Keycap Customization

The Smart Laffey D89 Series merges the visual and tactile prestige of a solid metal faceplate with the practical benefits of a detachable button architecture. Specially developed for luxury hotel suites, corporate boardrooms, and modern smart residences, the D89 allows individual metal keycaps to be unclipped and customized or replaced without disconnecting the internal wiring or removing the wall frame.

Universal Multi-Protocol Control Architecture

Engineered for effortless integration into Room Control Units (RCU) and complete home automation environments, the D89 Series provides cross-platform compatibility with KNX, Zigbee 3.0, Matter, RS485, dry-contact IO, and Tuya Zigbee networks. Whether operating low-voltage bus systems (12V/24V) or direct 220V AC mains lighting circuits, the switch delivers instantaneous tactile control over lighting scenes, HVAC, motorized shades, and guest services.

Key Features & Product Highlights

  • Detachable Metal Keycaps: Removable anodized metal button covers enable easy custom laser-etching for hotel service icons, scene names, or field replacement.
  • Multi-Protocol Integration: Fully native support across KNX, Zigbee 3.0, Matter, RS485, dry-contact IO, and Tuya automation systems.
  • Acoustic Noise Reduction: Integrated TPE elastic dampening component eliminates sharp actuation clicks for near-silent operation.
