Anyone build a dual momentary/latching switching pedal?

[powerplayj]

I want to build something like the Boss FS-6 to use with my Boss RC-2 Looper.  I really only need to momentary function but, just want dual switches in a much smaller footprint.  Anyone have a layout outlining the switching and jack types to be used?

it's preatty easy!

all you need are 2 DPDT momentary switches, which have on one side Normaly-Open and on the other Normaly-Closed.
A Footswitch switching between Ring-Ground and the other Tip-Ground. (Normaly-Open means that when you step on the footswitch you close the connection between the 2 contacts, vice-versa for Normaly-Close)

The "Polarity Toggle Switch" just switch between closed or open, which means it turn the side where the Ground is applied.



I had allready a footswitch like this, but wired ala "Normaly-Open", without the polarity switch. And just by swapping the ground connection that made the trick with my RC3, since the additional "Stop/Memory shift" switch works with the "Nomarly-Close" way.
That made me think at Boss they are idiots, because I had to break my head and search the web to find this out (at one point I started thinking my RC3 was broken....-.-), but on the other hand they are clever as well because if you don't know this you are forced to buy THEIR switch to work with THEIR products!
