The Smart Laffey D8B Series Luxury Metal Switch Panel pairs premium metal craftsmanship with versatile electrical engineering. Constructed from solid aluminum and stainless steel plates, the D8B Series features a refined large-panel design, layered TPE silent press mechanism, and seamless conjoined multi-gang mounting. Available in both standard high-voltage mechanical versions and intelligent KNX bus system configurations.
- Premium Metal Construction: High-grade stainless steel and aluminum alloy plates available in brushed and sprayed electro-plated finishes.
- Dual Operating Systems: Choose standard 250V AC 10A mechanical switching or integrated KNX automation bus protocol.
- Silent Press Technology: Layered TPE internal structure delivers crisp, quiet tactile feedback with every actuation.
- Multi-Gang Conjoined Modular Setup: Supports 1 to 5 gang horizontal and vertical continuous framing options.
Uncompromising Metallic Aesthetics and Intelligent Building Integration
The Smart Laffey D8B Series Luxury Metal Switch Panel brings modern architectural symmetry to high-end residential estates, luxury hotels, and executive spaces. Built with precision-cut aluminum and stainless steel front plates, the D8B Series provides an ultra-durable, fingerprint-resistant surface that elevates traditional wall controls into a signature interior design element.
Designed to fit universal 86-type electrical boxes, the D8B Series is engineered for both conventional 250V AC wiring retrofits and full-featured KNX building automation networks. Intelligent KNX models feature programmable LED backlight indicators that transition between dual colors (white when active, orange when idle) for effortless night-time navigation.
Key Features & Structural Advantages
- Solid Metal Architecture: Aircraft-grade aluminum and stainless steel faceplates engineered for scratch resistance and thermal stability.
- TPE Silent Press Mechanism: Internal shock-absorbing TPE layering minimizes mechanical click noise for quiet bedroom and office operation.
- Dual-Color LED Backlighting (KNX Models): Configurable backlight indicators offer soft status orientation without disruptive ambient brightness.
- 1-to-5 Gang Conjoined Framing: Snap-fit modular wall frames allow seamless alignment of switches, dimmers, sockets, and thermostat controls in a single continuous row.
- Fire-Retardant Sub-Base: UL94-V0 rated polycarbonate rear housing provides robust electrical insulation and fire safety compliance.
High-Voltage Mechanical vs. KNX Smart Bus Protocols
Select the configuration that matches your project requirements:
- Mechanical 250V AC Version: Rated for 10A line-voltage lighting circuits (1-Gang to 4-Gang in 1-Way or 2-Way switching modes). Direct replacement for traditional light switches.
- KNX Smart Bus Version: Operating on 24V DC KNX bus power, this unit communicates directly with central KNX actuators for scene lighting, dimming, shutter control, and HVAC triggers via ETS software configuration.

Installation & Mounting Instructions
Installation Note: For mechanical models, turn off main breaker power prior to connecting phase and switch line wiring. For KNX models, connect the standardized red/black KNX bus terminal to the rear module; configure physical address and group objects via ETS5/ETS6 software. Use 0.2–0.4 N·m torque when tightening mounting box screws to ensure flush faceplate alignment.
