Foot switch Disassembly:
The footswitch comes with a nice long flexible 3-conductor cable. But who wants a long wire on a wireless switch? So we'll start by cracking open the foot switch and removing the cable. You can put it in your spare parts bin to save for some other project.Be sure to hold the two halves of the switch together as you remove the pin so that the spring does not pop out!
Wiring it up:
The switch and the battery get connected by a few short jumpers. We'll add a key-code selection header so that you can easily reconfigure the switch my moving the jumper.Separate two jumper wires from the ribbon. Clip the connectors from the male end and strip the ends of the wires.
Solder one wire to the terminal marked "NO" and the other wire to the terminal marked "C".
Make sure to position the pins so that they angle toward the center of the EZ-Key!
Final Assembly:
Now we'll put the foot switch back together and package the whole thing up into a nice compact unit.(Optional step) - If you will be using this on a slippery surface, you may want to add some rubber bumper feet to the bottom of the plastic plate.
