[Collins] Wanted: KWM-2/2A Power Switch

[Dave Brown]

My solution to this problem documented here-
http://homepages.ihug.co.nz/~tractorb/collins/Collins%2075S%20mains%20switch%20.pdf

It might need some mechanical changes in the KWM-2 but you get the idea.
In retrospect I probably should have put the whole thing under the chassis 
somewhere.
