I've got a hot shot that had a few contacts that were loose on the switch blade, making intermittent connections. I was able to solder the contacts to the blades and it works properly. I had another blade the contact point fell out of. I had an extra point that I put on that blade and soldered that as well. Is this considered a reliable repair or should I change the blades at some point?

Effectively a reliable repair. If the blade itself is mangled or wavy, might want to replace the whole blade, but otherwise, you should be good.

Thanks.. The blades were in good shape and it looks like it took the solder well. On one switch, the Add hundreds switch on the score reel had a missing contact point. I replaced it with one of the small gold ones as this was all I had. It works, but I think this is supposed to be a big contact?

Might want to consider ordering a quantity of replacement contacts from PBR, or other vendor, to keep in your parts bin. Usually, about 35-40 cents apiece, but a good part to have in inventory.

Tap-tap-tap with a ball peen hammer -- good as new.

I did have a few to make up the light duty switches. My next order I'll get some others.

I can do that when its on the bench, but I didn't want to disconnect a lot of stuff. I'm surprised there isn't a special pair of pliers to compress the rivet.

I was able to peen a contact back on by holding the switch blade against a metal block and re-peening it in place. Was awkward though!

Might help for a 2nd set of hands

I just clean up then solder the loose contact to the leaf. The worst part (as you probably know) is finding those loose contacts.

Another way to fix some of these, a heavy pair of needlenose pliers, I squeeze/crush the contact as hard as I can, usually works. High current contacts I tend to replace, always have spare pieces on hand.

PBResource has new blades and contacts

I use needle nose pliers as well and pad the contact face with a piece of plastic especially gold flashed ones so the plier jaw doesn't damage it.

Thanks Howard. I did the repair to get the game running. I was wondering if my fix was a long term or short term fix. I have a few of the common switches in my next parts order to have on hand.
