This small LED torch came in for recycling. The batteries were stuffed. Cleaned the battery contacts and put some new ones in. It worked but not very well. It would flicker especially if the case was pressed. I took it apart, squirted some contact cleaner in the switch but it would still flicker. And then I noticed something.

The tab from the battery contact was shorting out to the LED PCB. It is thin metal so it bends easily. Either it was not bent down properly in the factory or it moved when the batteries were changed.

It was easily fixed. I bent the tab down and put a little patch of adhesive foam over it. We now have yet another torch that we can use and another item is saved from being recycled.
