Lithoss.
Designed for the room.
Built for your system.
Handcrafted in Belgium. Exclusively in the US through Florian Designs.
Eighteen finishes across every collection. Switches, dimmers, sockets, and smart control all from the same library.
Handcrafted in Belgium. Works with the control system already on the project.
KNX and Casambi integrated where specified, US-listed where required.
Twenty years.
The same workshop.
Lithoss was founded in Pittem, Belgium by Bart Spillemaeckers, an electrician who set out to design the switch he could not find in any catalog. More than twenty years later, every product is still made in the same workshop by the same people.
Every product is made in Belgium from start to finish, shaped by artisans who sand, polish, etch, and treat each surface by hand. Brass develops character with use. Anodized aluminium holds its color permanently. Antique finishes are chemically aged, not painted.
The materials interact with light in ways that shift subtly across the day, creating a tactile presence that a photograph does not fully capture.
Six collections, 18 finishes. Every combination.
The original Belgian square frame, US-ready with a mudring adapter. Available in three frames: Select, Opera Select, and Circum Select. 24V dry contact, KNX, and Casambi. UL listed on 24V single-frame variants.
A vintage toggle profile with cone and knurled detail. Mechanical dry contact, compatible with Crestron, Control4, Lutron HomeWorks, Savant, and RTI.
The accent piece. In the same finish as every Select keypad in the room.
Up to 12 individually engravable buttons in a single frame. The hospitality keypad. Scene names, room labels, and function icons — all in the same finish as the rest of the specification.
Rotary dimmer in cone and knurled profiles. KNX controller, Casambi wireless, and mains variants available. The dimmer in the same Bronze Antique as the switch beside it.
Outlets, USB-A/C, HDMI, UTP data. Cover plates in all 18 standard finishes. The piece that closes the specification.
Gatekeeper, Nightguide, Q Light. Orientation lighting for thresholds, corridors, and landings — in the same finish as the Select keypad at the room entrance.
Specifies into the system
you already use.
Whatever control system is on the project, Lithoss integrates into it.
No bridges. No gateways. No lock-in. The finish, frame, and engraving stay the same regardless of what is inside the switch.
Works with the system you're installing.
A momentary dry contact signal compatible with every major US control system. No additional hardware at the switch location.
Two wires per button into the I/O module already in the rack. With or without LED feedback in white or amber.
Chip-on-board. No external module.
The KNX chip is integrated directly onto the PCB. 29V SELV, NEC Class 2. RGB LED feedback. Optional temperature sensor. ETS-programmable. One device. One SKU. No module to source, mount, or wire separately.
Bluetooth mesh. No bus wiring between keypads.
No low-voltage wire between keypads. No gateway for local operation. Battery variant requires NEC 210.70 review for code-required locations. Mains variant operates continuously and functions as a mesh repeater.
Specify the finish once. The technology variant follows the control system on the project.
Etched into the material.
Not printed on it.
Engraving offers a refined way to personalize buttons and cover plates with text or symbols that become part of the material itself. As each surface is etched, the underlying tone is revealed, creating a subtle contrast that adds a crafted and enduring detail to any interior.
Engraving adds approximately one week to production. Orders may be placed with engraving specifications to follow — production begins on the mechanical and finish work immediately.
