HP41c Zebra - last tests

[Jose Gonzalez Divasson]

Thanks for the tip!! I was trying silicone tubes so far, but yours is more elegant.

2mm is slightly on the high side, since the circuit is 0.13 mm x 2 = 0.26 and then we get 2.26 mm. Original is 2.1mm, "giving" down to 1.7mm when pressed

I'll try with 1.78mm found in RS Spain
