For those of you that have a Reliant switch with the control box, I've come up with a method for making it removable/replaceable. It's simple, cheap, and works well. Here's what you need.
1)8-32 Square Nuts
2)2mm thick rare earth magnets
3)sandpaper
4)5 minute epoxy.
Start by removing the card from the control box. It's held in with CA glue (Krazy-Glue)so just a couple of taps on one end with a screwdriver will break it free.
Remove the control box screws and remove your control box. Lightly sand the back of the control card to scuff it. Remove the glue traces from the box so there's no build up. Mix a small amount of the epoxy and hardener together. One or two drops of each will be sufficient. Place the magnet on the square nut. Apply just enough epoxy to the bottom of the square but to make it wet but not so much that it gooshes out everywhere when you put pressure on it. Place the square nut/magnet between the screw holes in the control box. Dab epoxy on top of the magnet. Place control card back in the box. Squeeze together for about 5 minutes and then let stand for about 10 more. When done, you should now have a magnetic mount for your card so you can take your control box on and off at will without having to reglue the card over and over.
