Hi everyone! I’m trying to do an external Aux Switch for my timefactor but It doesn’t work. I have a stereo jack connector, 3 normally open switches, 2 1N4001 diodes and a trs cable. I followed the digitech fs300 schematics but when I plugin in the switches and try to assign each of them the display shows “T+R” for a while (while I Press the switch) and then goes back to the previous setting (RNG).

Please just buy an FS-300 and save yourself and us a lot of trouble.
There may be reasons why you can't do this that are beyond my ken. In this case, I would suggest that your RNG switch is probably shorted or, (apologies), maybe miswired.

As I want to mount the aux-switches on my pedalboard without additional housing:
@camn are you willing to post the schematic voodoo for me?!?

I am traveling now.. but I can make one soon.
But as mentioned.. if you dont already have parts- I would use two singles and a double throw switch for this.
DO you have parts already, or no?
And what are you mounting in? Wood? Metal?

No I don’t have the Parts yet – I’ll mount it on a pedaltrain. As I’m electronically skilled I’ll be aware of shorts and do isolate the components.
I would really appreciate your schematic

ok its easy as pie.
You need AT LEAST one of these:
But you could use that switch for ALL THREE if you wanted. But you need at least one. FOr the other two you can use this:
Then you wire them up… here is a quick skectch… but it is totally easy:Show More...Show Less...

That’s great – thanks a lot for the information @camn!
May I conclude: the DPDT simply closes Tip+Ring simultaneously to GND, just that simple?!
As I’m from Germany, I will search for this momentary switches somewhere ’round here. But now it’s clear

yes exacly so- the DPDT handles two separate circuits with one press… which is the only special thing about the third switch.
There is probably a reason people use the diodes instead.. but considering the DP only costs 4 cents more.. I cant see why we should!
