The plastic button used to turn my older TomTom GPS (XL 340) on and off broke about a month ago and I was unable to find a replacement. I figured out that the plastic button which broke was used to push a small switch attached to the circuit board inside the GPS (see picture one). I started using a small toothpick to push on the switch to turn the GPS on and off and it worked for several weeks. Unfortunately, I pushed too hard with the toothpick and eventually broke the solder points of the switch to the circuit board and the switch detached from the board (see picture 2). I figure I could try to solder the switch back to the board but I am afraid that it will just break off again. Is there a way I can solder wire(s) to the board that I could simply touch the wires together to turn the unit on and/or off or is that not the way the switch and circuit interacted? Or can I somehow solder the board contact points in such a way that the GPS just turns on when I plug it into my cigarette lighter? I've included a picture of the back side of the board if it is needed. Thanks for any guidance anyone can provide.
