It looks like you used the
MadBean Wiring Layout, so when you arrange you pedal vertically you should imagine the lugs on your 3PDT switch numbered like so:
A B C
1 - - -
2 - - -
3 - - -
When the effect is bypassed, there should be continuity between 2A & 3A, 2B & 3B and 2C & 3C. There should not be continuity between 1A & 2A, 1B & 2B or 1C & 2C.
When the effect is engaged, there should be continuity between 1A & 2A, 1B & 2B and 1C & 2C. There should not be continuity between 2B & 3B or 2C & 3C.
Testing continuity on those lugs for both switch positions will confirm that the switch is (internally) functional, but you could still have cold solder joints on those lugs. Test continuity between lugs 1B & 3C, between the Tip lug on your Input jack and 1B, and between the Tip lug on your Output jack and 2C. These should have continuity regardless of the switch setting.
The grounding on the switch must be working because the LED is lighting when the effect is engaged, so I didn't bother with asking you to test those lugs, although we may have to come back to them later.
I also just noticed how perilously close the Tip lug on your Input jack is to the case wall. Please make sure it's not shorting against the case. Good luck!
