Wiring Repair

I have a switched 12V doubler with a USB socket mounted in the front of the car. Using this I can plug in my Garmin, dash-cam and phone all at once. However, recently one of the sockets failed.

The double shows a red LED by each switch when they are off and a blue LED when they are on. The blue light on the failed socket wasn't coming on so I decided the problem was likely to be related to the switch.

A quick disassembly revealed a broken track. Now I may not know how to repair a broken track on a circuit board, but I know enough to realise that I could bridge the break by soldering a piece of wire between contacts either side of the break.

Soldering didn't take very long and very soon the unit was back in the van and as the picture shows, both lights are blue.
