Lithoss nv/sa is a Belgian manufacturer of handmade architectural light switches, sockets, dimmers, and related KNX/home-automation controls, headquartered in Pittem, Belgium. Founded by installer Bart Spillemaeckers to meet demand for exclusive, timeless switches, with its first series (Select) setting the template for the company's later ranges.
Lithoss's flagship / first ('the first series') switch and pushbutton collection: a solid-metal frame + pushbutton module + cover-plate system in a clean, simple square design. Designer credited as Bart Spillemaeckers.
A reinterpretation of Select with pushbuttons flush with the coverplate rather than raised, for a perfectly flat, sleekly-integrated surface.
Aviation-cockpit-inspired switch collection with toggle (2-way), shutter, cross-switch and pushbutton variants, distinguished physically from Select/Squares by its conical or diamond-knurled toggle/button caps.
A minimalist switch collection with smaller pushbuttons than Select, sharing the same overall quality/finishing but a distinct, more compact button design.
An award-winning (Henry van de Velde label) switch design built around the square as its basic form, designed by Pieter Stichelbaut and Matthias De Buck.
