I posted this in the “everything else” forum and didn’t get much of response, maybe someone here can help out.
I’m looking for a 4 position rotary switch to build an A/V selector. Does anyone know of a suitable switch I can use? Do I need 6 pole to separate all the grounds or can I make them common for each component?
I would just like to build a simple box with 4 inputs ,1 output and a rotary switch to select different source components.
Thanks,
Rick

Old fine
I have started using some really nice old switches. These are Centralab steatite bodied switches. The contacts are all silver plated.
On ebay these sell for anywhere from 2.00 to 10.00. A dual pole, 4 postion switch non-shorting.
I like to wire mine up like Croft does their preamps. Use an old number of positions, and wire every other position as a ground. This makes muting real easy. I have used both shorting and non-shorting types.

Break before make, or make before break, is what we usually call them in the UK. That should make more sense to you? For an input selector you want break before make.
Shorting and non-shorting switches
On rotary switches the shorting or make before break switches have a wider wiper. This allows the wiper to contact both positions as it moves.
Most switches are non-shorting.

Rnickl,
You are in the same area I am in.
There's a very high quality 4pole nonshorting grayhill switch that is sold at Anchor electronics for only a few bucks. It would serve your purpose well. Look them up or shot me an email and I can direct you there.

Thanks for all the info guys.
Any chance you have a part number for the swith oaktsh? Chances are good they don't stock many 4 pole grayhill swithches anyway. I know where Anchor is and thanks for the tip.
