It is a focused tool for composing generic European-style switches, sockets and data modules as complete SketchUp assemblies. Free includes 1–2-position frames, horizontal/vertical layouts, all current modules, low/high detail, finishes, dimensions, mounting height and local presets.

Target: desktop SketchUp 2021+ on macOS and Windows. Current hands-on validation is SketchUp 2026 on macOS, so feedback from Windows and older versions is especially useful.

I am also recruiting a limited group for the time-limited PRO beta (editing, batch tools and reports). Please use the registration form on the product site rather than posting your email publicly.

SwitchBuilder is manufacturer-neutral and is a modelling/visualisation tool, not electrical design or certification software.
