3pdt switch to switch transistors whilst playing

[Widows]

Hi, I want to add in an extra stomp switch to a fuzz circuit I'm building to allow me to switch between 2 different transistors whislt playing.

I had a look on Beavis Audio and their page has a digram (link below) to show you how to wire a 3pdt for this purpose
http://www.beavisaudio.com/techpages/Switches/  <--- look about 3/4 of the way down the page
I wired the transistors as shown, making sure the lugs were flat rather than vertical and connected 3 wires in the middle 3 lugs, and a transistor to each of the 3 lugs on either side.
Unfortunately, when I connect the switch, I only get a clean sound on one setting, and nothing at all on the other setting. I probably have one of the transistors the wrong way round which is causing the sound to cut out in one of the two switch positions, but why would I only be gettting a clean sound?

I checked the gallery after reading another post and found this:

It appears to show the same thing but there is no indication as to the orientation of the switch or the lugs.

Can anyone enlighten me?

Cheers

For your second example the switch should be in this orientation, so one transistor connected to the top 3 lugs and the other connected to the bottom 3. If in doubt check the switch with a meter.

aah! I had the switch in the same orientation but had the transistors going down the sides rather than across the top, silly me. I'll rewire it tomorrow and test it when it's not 2:30am.

cheers dude

just a quick note that I have never had to use more than  a DPDT to switch transistors and I've used a SPDT many times, leaving two leads down of each and just switching between the 3rd.

If you have transistors in parallel, you could wire up the collectors together and wore the emitters together and use a DPDT switch to connect the base to the emitter or the input source.  This assumes transistors with low leakage (meaning silicon).
