Drop the speed controller and go with my diagram, I don't think that it will be easy to link the drill reverse to the TV lift.

Could you just expand on this a bit Bob. At the moment I have a positive and negative going into and out of the switch unit, which is taped fully on, and which serves no control function for my set up. I'm really not sure what it brings to the party.

If so, I'd rather go out and buy a commercial lifter as don't have the skills necessary to safely go playing around with 240V. DaveL has supplied the 2 way microswitches, so I suspect they are properly rated for the job in hand. Therefore I'm not sure what problem I would be avoiding by doing the on-off switching on the mains side of the transformer.

Indeed, although I tested your patience more than once.

If you fancy doing some DIY electronics there is this very good value evaluation board which will drive a motor in both directions up = to 35A - which should be fine. This would replace all the power switches and reversing mechanism you have now.
