Installed AICO Ei2110e modules some 6 years ago and used their RadioLINK bases to link one set to others in the extension.

Unknown switch Discussion ThreadUnknown switch Electrical Advice

Does anyone know this switch?
It was used in the 1960s by my father to distribute power to either one or two lamps. In one position, one lamp would burn at full intensity, in the other two at half intensity.
