Switches
« on: August 06, 2013, 11:33:22 AM »
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

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?

Yeah, well, you know, that's just, like, your opinion, man.

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
