I'm sure the repair for the Cherry switches is similar. However the dead switch I had was a Licon 01-700157 these are the clicky kind.

The switch was intermittent, and the LED was dead.

First you need to drill the rivets holding the whole thing together. Just drill the flanged portion off.

Push the rivet through and remove the switch, and cover from both sides.

Now you can see dimples where the led leg lugs are hot melted into place. I used a .046 or #56 drill bit to drill through the middle of the hole, through the hole in the leg, out the other side. I was then able to push the lugs up through the plastic holder to remove the LED.

Remove the old LED, and trim the legs of the new one to bend into shape and solder on the lugs.

At this point it's good to know which side is the cathode, and which is the anode as the mounting base is labeled with a + so you know where to hook the + lead.

Re-insert the lugs, and use either hot glue, epoxy, or heat up a punch to re-melt the plastic to hold the lugs in place.

You can now remove the switch assy, and burnish the contacts. This does not mean sand them down. If you don't know what burnishing is google it.

Now put the whole thing back together. You can buy new rivets if you want to goto the expense of buying riviets and the set tool. I just re-used the old, and used epoxy to hold them in place.

Now I have a button that works all the time, and the led lights up. Plus I didn't spend $20 on a new one. $20 bucks?? Really? 10 cents on a new led, and 30 mins of my time.
 
i just took mine apart and went to radio shack to try and find an LED. There were different voltages to pick from. I ended up buying one that is 2.6 volts 28 ma 10 mcd. Will this work or should i gotten a different voltage.
 
threads like this get lost and buried cuz of time itself. sure it's 10 years old, but the info here is very relevant and current to today's collectors! bump for a stellar tutorial on this sir!
Bumped for bumping. I learned something new today thanks to this.
