Two ways to switch the same lamp from several places. Both circuits below actually work — click any switch or panel. Then press add a switch and watch what each philosophy has to do about it.
strappers, intermediates and a live path frozen in copper
one bus cable · one relay channel · links made in software
Concept animation, not an installation guide — live-side conductors only, routes illustrative, regulations and containment out of scope. Every Velbus link shown is a real “0104 Toggle” action taking under 30 seconds in VelbusLink, and every panel LED follows the relay’s status broadcast — all N switching points always show the lamp’s true state, something copper strappers have never managed. And as the source presentation puts it: 20-way switching is no harder than two-way, just repeat the steps.
