Reset 2-pin Wire
Use a 10-wire silicone cover stranded-core ribbon cable. Cut a piece so the cable has a length of 6cm(2in). Then, peel off a 2-wire bundle. Use this wire to connect the metal ball tactile button.
Reset Wire Tinning
Using wire stripper, remove a bit of insulation from each wire. Use a third helping hand tool to keep the whiles steady. Add a bit of solder and tin the stands of wire. Pieces of heat shrink tubing will keep the wires bundled together.
Secure the metal ball tactile button to third helping hands or a panavise to keep it in place. Tin two of the leads on the button (the side where the leads are protruding). Then, solder the wires to the two leads.
Check the wires are properly soldered. The solder joints should be solid. A piece of heat shrink tubing will keep the wires bundled together.
