Mercury switches are pretty basic things. an 'intermittent' mercury 
switch is most likely caused by incorrect mounting, bad leads or 
something like that. The usual type is a sealed glass ampule with the 
mercury happily bobbing about in a vacuum. When the device is tilted 
one way, it makes the contacts, when it is tilted the other way, it 
breaks them.

As for the specs, according to the wiring diagram, the mercury switch 
is switching the ground for the relay, not the high current of the 
defogger. So, probably anything you could pick up from Radio Shack 
would work.

Check that it is mounted properly. I haven't seen one of these, so 
I'm just going by basic troubleshooting techniques.

I don't know if this thing can rotate, but it's possible that if it 
is rotated to the wrong orientation that the contact would not be 
complete.

As for the 9-3, there are so many switches, relays & sensors to tell 
the car (and then the druver, via the SID) where the top is, that I 
doubt they need something as simplistic as a mercury switch...

It's strange that Saab discontinued this part, though.
