The track don't join each other, no pins.
Both the piece of track that's stationary on the bench (Both sides) and the piece that's stationary on the lift will be spaced very close. You would cut them straight and flush with each other. (No direct contact) That let's the lift go up and down. Also, A power and common wire will need to be attached to the stationary track that's on the lift portion. That alleviates the open power in the circuit.
I hope this makes some sense. It's a lot easier than this explanation. I'm going to go back and see if I can find some pictures. If I do I'll get them to you.
