This is a remix of the Frankenstein Switch modified to fit what I believe to be a European style light switch (or at least all the light switches in my house). Aside from the different size, the nubbin doesn't have anything to clip onto, so instead it pivots on a central axis, The nubbin will require a short 2mm shaft to act as a central axis. The screw holes are concealed beneath the the switch, which is the same file as the main part.
