[TenTec] Corsair 2 bandswitch contact problems

[Jos Weitenberg]

I have a problem with the bandswitch of my Corsair 2
It cracks and receive will fall away.

Is it possible to solved this with an contactcleaner ? And wich type 
contactcleaner can I use ?
I have read in the archives to use the red and the blue sprays from 
Cramolin, but is this still avaible? and is this avaible in Europe ?
