Well. I have always wondered about this since the DTXpressII TP65S 
pad, with its two rim switches and one piezo.

I suspect it's fancy electronics making a single "switch" on 
ring/sleeve distinguishable by the module - perhaps level-based or 
something - rather than say tip/ring for the second switch.

The reason I say this is that I have a Pintech SE-102 pad as a snare 
on my DTXpressII module, but I leave it set up as a TP-65S pad type. 
The SE-102 is a stereo pad with a single rim switch, so I should 
just get the rim1 sound every time I strike the rim. However, every 
now and again, I get the rim2 sound when I strike the rim. I haven't 
pinned down the circumstances in which it happens, but the fact that 
it does suggests it can somehow distinguish rim1 and rim2 on the 
ring/sleeve combination.

OGD, anything obvious from the circuitry when you disassembled yours?
