Hi Pekka
the switches look OK - I assume they are break before make
twice I have resorted to making a custom switch using parts from RS Components

an expensive solution , but it worked

Those "Wafers" are not silly money, but shaft and rest of it will add up. But they are higher voltage and probably lower capasitance etc.

What about post weld heat treatment? Have you got a heat blanket to wrap the board in for stress relieving.....?? :lol: :lol:
Sounds like you are all having fun.... :dremel: :zap: :beer:
RobWilson:
:lol: I was planning on peening the welds to relieve the stress John .
My Buck converter power supply arrived a few days back , opened it up and it has surface mount components :palm: , so a quick shop on Ebay fro some new gear ,
one has to buy new toys :dremel:
And some tackle to practice with .
WTF !
