I would like to know if there is a schematic or, preferably, a perfboard, veroboard, or PCB design for a latching relay based true bypass on a pedal.
There are some schematics for non-latching relays like R.G. Keen's: http://www.geofex.com/FX_images/relay%20true%20bypass%20with%20Boss-Ibanez.gif
More info about this particular schematic here: http://www.diystompboxes.com/smfforum/index.php?topic=86288.0
However, I also found this diagram: http://www.geofex.com/FX_images/relays2.gif
It does not specify if it's designed for latching or non-latching relays. Moreover, and given the other circuits I've seen, it seems way to simple to work. It would be awesome if it worked for individual pedals.
So far, the only latching relay design I've seen is this one: http://www.fredric.co.uk/
However, it is for a two coil relay. Unfortunately, only a one coil DPDT relay is available in my third world country (where, ironically, a lot of electronics are made, exported and then imported again).
Would you please explain to me what I have to do to apply this design to a one coil relay?
To sum up:
1.- Have you seen any latching relay based true bypass schematics/perfbord layout/verboard layout/PCB?
2.- Would you tell me how to modify the attached design to apply it to a one coiled relay?
