The connection sequence for an RS60E3 is:

Shield
Shield -> Ring
Shield -> Ring, Shield -> Tip

The switch has two positions -- half-travel and full-travel. At full travel, 
both contact pairs are closed. At half travel, only the focus pair is closed.

I could swear I'd seen a copy of the internal schematic of the camera, at 
least as far as the shutter circuitry goes. Maybe try camerahacker?
