We have limit switches on our lift as well, actually four. We used some long-lever switches from Jameco and bent the arms up about 45 degrees one needle-nose-plier width beyond the end of the switch, and down about 90 degrees another plier width down. It ended up looking something like this:
Code:
 
   _________/\
  ┌───────┐   \
  │       │    \
  └───────┘
We mounted this inside our lift channel beside the place where our lift plate passed. As the plate reaches the switch, it pushes back on that 90 degree bend, activating the switch. The long lead at the end keeps the lift from jamming the switch on the return stroke, which was a problem we had with rollers that weren't precisely aligned.

Edit: I attached a photo of how our roller limit switches were mounted.
