Is there anything like a ON-OFF-ON switch array, like a DIP switch Package?

Just a thought...  Could you have default caps in the circuits at all times and use a DPST switch to connect caps in parallel?

Yeah, historically I have been doing it like this for when its just one or two caps that need switching and I have room to panel mount


But I'm trying to do as much as I can onboard and have 10+ places caps need 3 options I was thinking more like this



Just seeing how small a footprint I can go with cap switching options.

if you are only ever going to have one capacitor active at any one time, why not try to rig up a rotary switch circuit ?

As I only need 3 selectable capacitance ranges on each node but need 10+ nodes, so the footprint for 10+ 3 position rotary switches is a little prohibitive, but rotary switches are awesome!

Would totally be viable if I only had to change a couple of values by a large range, but I'm in the situation where I need to change a lot by a little

i see - it seems to me you already have the solution in your own Reply (#2)

if you want 'robust', you have to pay for it - i would imagine fiddling about with 10 nodes and very frequent physical changing of positions will cause considerable wear & tear - probably why those mini-switches you found were "well expencive"...
