Tks. I'm going to buy a 10-step sequencer kit & want to modify it. As is, you have to patch the last step # with a 1/8" cable & short it to an "end-step" jack. I want to take the jacks out of the design & replace it with a simple rotary switch instead.
There's a much easier way to do this: use a 1P12W. You only need to switch the signal, not the ground of the step-reset jack; and 1-pole 12-ways are much easier to find.
Whatever's to hand, or easy to find, or cheapest for you.
All you need to do is take the outputs from the steps, put them on the "throw" pins of the switch, and put the "pole" pin of the switch to the reset input on the counter. You don't need to shield this connection so a 1-pole is fine. As for using a more than 10-way switch, it doesn't matter as you just ignore the extra pins. There's typically a ring around the neck of the switch that you drop in place to limit the rotation of the shaft to the right number of steps.
This is what I use. Your local supplier will likely have something very similar.
I need a 2P10T rotary switch
