I'm building a moving coil step up transformer using some Cinemag CM-1254's. The basic schematic is here: http://cinemag.biz/phono/PDF/CM-1254%20Hookup.pdf (http://cinemag.biz/phono/PDF/CM-1254%20Hookup.pdf)
I was going to hard wire it all, but I think I'd like to set it up with a switch to change the gain. Does anyone have any recommendations for good quality double pole double throw switch?

I have used silver contact switches from this source, the one I was thinking of is not in stock SW-3 (ITT-NOS) , but I have used the VR-S2x5G as an input switch. http://www.vt4c.com/shop/program/main.php?cat_id=60&group_id=2&hit_cat=
Parts connection does something similar http://www.partsconnexion.com/CONNEX-75575.html
Elma make good switches too and I am sure that there are plenty more

i generally stick with NKK since they're nice quality and easily procured from Mouser or Digikey. for rotary, i like Grayhill. i sometimes use the latching (not momentary) push buttons from Bulgin.

Perfect, thanks guys. That should get me squared away.
Man, 5 week delivery times from Cinemag right now. David says they are swamped. I like their stuff, and his customer service has been great for me, so I think I'll stick with the wait... but that sucks!! ha ha
