I used to make button / keytops by making a mold of a compatible one in clay or silicone rubber and filling it with epoxy followed by a lot of fiddly work carving out the interface to the keyswitch plunger.

These days 3D printers are your (frustrating) plastic pal who's fun to be with.

Mark,

Yes, my fall-back position is to do a 3D design (the tricky bit will be the bit that locks onto the plunger, and the transparent circular window for the LED light).

If anyone ever decides to set up 3D printing for Wavetek 1281.1271, 4920, and 4950 they would have a small gold mine on their hands. Those buttons all discolor very badly make a great instrument look old and dated. If they did them with the writing recessed in a contrasting color, which should be easy with 3D printing they would breath new like into these meters. I myself would buy at least 10 sets.

Cheers;

Thomas Knox
