Imagine the following switch. It has N positions, let's say 5 positions and 5 contacts A, B, C, D, E.
Position 1 does not connect any points. Position 2 connects A and B Position 3 connects A, B, C Position 4 connects A, B, C, D Position 5 connects A, B, C, D, E
This switch would be useful for connecting caps in parallel to get adjustable voltage. Do such sqitches exist and, if so, what are they called? Can I build one from a regular 11 position switch, by some means that I am missing?
thanks
