Thanks Tom, however,

Those who are into diving will note that top end dive computers (eg the
VR3 http://www.vr3.co.uk/ come with the same sort of switches I'm
talking about. This Camera Housing is rated down to silly depths (150M).
The Housing is aluminium and never thinner than 5mm. You need Big
Positive buttons - think about cold fingers in neoprene gloves.
I'm also a Dive Instructor (and own a VR3).. (but thanks for the info).

...But this is all off the subject - Has **anyone** got a complete
archive of the mailing list that I can download???
