Switch (DPDT) only works when held down

[kb19]

I'm converting a wah to true bypass and have wired everything to what I think is correct. I have done this on one wah pedal before (same model), and have it here next to me for reference. I can only engage the effect when the switch (DPDT) is depressed (when I release the switch I just get my dry signal). I'm not at home so I can't upload a photo, but I feel like this might be a common / easy problem?

Any ideas?

Thanks

You might have used a momentary switch rather than latching? does it click? otherwise it could just be a bad switch I suppose or overheating of the lugs caused it to fail internally.

yeah it does say momentary, and that's what I thought the problem was, but it looks exactly the same as the one I put in my other wah. I just went and asked for a DPDT, *sigh*

Yeah... they look the same, you want a latching switch, that means it clicks on or off, momentary are only on aslong as they're being pressed.

Oh well, atleast the problems solved  and welcome to the forum.

fffffff, and it was 10 bucks!

Thanks a tonne. I'm under a serious time constraint to get this out by the end of the week so I might be posting here again if the other mods don't go as planned (led / external power / "secret mod" haha).

Thanks!
