ABY box issue

When I hit the switch for a and B both amps come on. When I hit the switch for a or B I can get A to come on but not B. I'm wondering if there's anything really obvious that I may have missed. Any help would be greatly appreciated thank you

Use your multimeter at the switch lugs to check that the switch is working. You may have damaged it while soldering.

Another bad switch I bought four switches and two went kaput! At least the box works now.

When I first started building pedals, I probably destroyed at least 4 of those switches before I improved my soldering skills.  All of my switch failures in the beginning were caused by getting the terminals too hot. I haven't destroyed one of those switches in about 6 years.
