Very nice, just what I would have hoped to achieve if I still had the
switch caps:-)

Hello, this is my first message on this list,
I've read the recent thread about racal dana's switches,
this is the way i've done it:

A little crude but in a pair of hours i swapped all the switches.
To obtain the proper tip shape to fit the original caps,
i cutted a cross in a 2mm thick little brass plate and
fixed it to a soldering iron, found the correct
flow temperature of the plastic and the work was simple.
The switches are normal 6x6mm tactile, only they tend to bounce sometime.
Fabio.
