Hey all - posting this here because it has to do with a phono pre preamp (Boozehound) that I am adding a few things onto.
I need a 6 position selector switch. What I want to do is to be able to select the cartridge loading from the front via a selector switch. I have some dip switches that I could use inside of the case, but I would like to do it from outside of the case for convenience. I have been looking for a rotary switch with 1 pole, 6 throws, and 2 decks. I want one power source or input, but I want to switch that source through 6 separate 'channels'. I've been having trouble locating a switch that can do this. Have I been looking for the wrong type of switch? please advise! Many thanks!

Hi, it sounds like you need a 2 pole 6 way switch (I presume it's for stereo). Most switches are used to select one output from a number of inputs but there is no reason you can't use it the other way round
It sounds like you need a 6-position, 2-pole switch. Like Mouser p/n 706-56D30-01-2-AJN. It's 2 poles on a single deck. If you need 2 poles per channel, then the same switch, but with 2 decks.
All the best,

For switching small signals, it is best to use switches with gold-clad contacts, as these don't oxidize (prevents cracking sounds after a year or two of use). The one suggested by GOR3 has gold-clad contacts.
6 throw is 5 inter-throw gaps. At typical 30 degree between positions, this is 150 degrees. So two such switches can fit in one deck, yin/yang. Indeed most economical switches are 12 outer contacts (360 degrees), with 1 2 3 4 or 6 poles for 1P12T 2P6T 3P4T 4P3T or 6P2T.
Multi-deck switches still exist; but getting very hard to find, with the config you like, maybe a price you don't like. I suspect they were over-produced in the 1960s-1970s. Distributors thought they could cover "any" need with a few standards and a few extra wafers and shafts. But commercial products tend to even more complicated switching needing custom contacts. PICs turned design away from simple switches to buttons and displays. I think distributors got tired of carrying inventory which was not selling, and cut-back to only the few standard configs you can do on a single wafer.
