Thank you for the picture. That is very helpful.
Here is a picture of the traces on the PCB (in red). Make sure you are getting continuity between all the points on the switch and power jack which should be connected. It seems like there may be a broken trace from the jack to the switch. You probably will need to use the pointy end of the meter’s probe to dig into the solder joint to get past the layer of flux, so you can get an accurate reading. If you do find there is a broken trace somewhere then you’ll have to run a jumper wire between the 2 pads that the trace is supposed to be connected to.
The 2 pads on the switch that have traces attached to them are the 2 pins that should be connected when the button is pressed in. Test those for continuity.

Let me know what you find.
Good luck!
I’ll be out of town for the next week, but I’ll try to follow up when I get the chance in a day or 2.
