I was making some variable frequency electromagnets and I wanted a quick and dirty way to hook them up. So I bought the parts I needed from Sparkfun:
1.) Rocker Switch - SPST (round) 10A 125 VAC, Part Number: COM-11138; Quantity: Three
2.) Terminal Block - 3 Position (15A, 600V); Part Number: PRT-13060; Quantity: Three
You also need some 3mm nuts and bolts to hold the terminal block down. I forget what length I used as they were just something laying around.

I used a brim and printed it directly on a glass plate.
