The little plastic nubs in the keyboard of my NSM Concert 240-III are breaking down, causing a couple numbers to be intermittent, and one to stop working all together. When this first became an issue, I could rotate a key 180 degrees to get the spare nub to actuate the contacts, but now I'm running out of spare nubs to keep it working. Has anyone found a suitable replacement for these nubs? The NSM manuals don't seem to have an exploded view of the keyboard, and I haven't found anything that specifies the material or diameter of the nubs. Attachment Deleted |

Did you check with any of the parts suppliers listed in FAQ's above-- I would ask Hildegard, in Germany --if they are available, she will most likely know-- Ron Rich

I thought this was a community where we could ask for help. I'm well aware of the dealers listed in you FAQ, but I'm asking if anyone has alternatives. I guess I should stick to the Facebook forums where people are friendly and offer help. |

There is a video on YouTube of someone carrying out repairs to similar NSM pushbuttons. I haven't actually listened to what the repairer has to say, just gave it a cursory look with no sound! One thing I would say - I wouldn't dream of drilling out the old posts, as he does, without using a proper bench drill.

Just thought that I would follow up on this having just repaired one of these keypads. The little posts that are installed in the buttons are quite soft so can be easily drilled out by hand. I used a 1.5mm drill (1/16" would also be fine) rotated by finger and thumb to reduce the chance of any disastrous accidents. I then carefully picked out any residue using a small jewellers' screwdriver. I replaced the posts with small pieces of 1.6mm nylon strimmer chord (from my local garden centre) glued in place. I picked up the strimmer chord tip somewhere recently, I can't remember where - but it worked a treat!

I just finished doing a quick repair on a keypad. I used wooden matches. Snug fit and I just trimmed them down with nail clippers to the right length. You can buy a repair kit on Ebay but its 20 dollars.
