Step 3: Resoldering Micro-Switches If a switch has actually fallen off, it needs constant hands. The switch should be lined up with the solder pads on the board and carefully re-attached utilizing a fine-tip soldering iron. Care is required, as extreme heat can lift the delicate copper traces off the board, messing up the remote permanently.
