Ray- If you want just two inputs, a DPDT toggle switch rated for 5 amps or more is great. I doubt it would ever wear out. I never liked rotary switches, but if you were to go that route, get one with exposed contacts so you can clean them from time to time. BlairThanks Blair, The switch that was mentioned to me had an open frame. Somewheres in the $20 range. That's all I can remember. I guess I could search through the Lab threads and see if I could ffind it.Thanks.Ray

I remember someone saying that a closed switch assembly doesn't make for a good audio switch.
It's gotta be a make and break type switch.
I am assuming you'd really only need a DP3T switch for 3 sources. Two poles (for hot, neutral) and three positions on-on-on. I believe they do make these switches. I have a 4PDT switch, so you can get all crazy with switches.
You definitely need a break-before-make switch for a selector, otherwise you would have two sources mixed together for an instant during the switchover. That might cause damage to a source.I, too, am building a selector switch right now. I'm building a stand-alone source selector switchbox for use with a Manley Steelhead's auxiliary input. This will replace my SAS 10A if it sounds good.The best selector I have ever seen is a DACT CT 3-5-4. It has 5 positions, break-before-make, and has poles for both the signal and the ground for each source. This enables you too keep the grounds isolated from common going through the switch, that is, you can keep both the signal & ground or shield connection from each source separate from the other sources. The construction quality of the switch is superb.You can find a few vendors on the WEB, including DIY Cable. It sells for around $115.I vouch for DACT in part because I replaced the Noble pots in my SAS 10A with a DACT step attenuator and obtained a significant improvement over the already high standard of the unit. You can also motorize DACT switches with a quiet, proprietary stepper motor.Hope this helps,Dave
Elma is $39 at Michael Percy.It may have been cheaper before last year's fuel and metal rallies.My GG sounds quite good with the stock selector. Try it first, since it's included in the kit anyway. An ALPS 4 position stereo selector switch is available from Mouser for $9. I used it in a Pass B1 kit, works fine.
