Watching a group of Techs and Mechanics refit the Reversers back on a RR TRENT 732 the other day and they had finished refitting and they had the pumps going on the blue system ACMP I think, and the Tech who was in the cockpit signalled down to the Tech on the ground who in turn operated a switch on the engine and then the T/R 's were being tested ,what switch is this?

that is a safety switch, installed to make sure somebody stands close to the engine and watches nobody puts an arm in the T/R door when the T/R is operated from the cockpit via MCDU interface.
The system goes inert after a while though and you have to start over again to make the things move.
But what do you mean by Trent 732? Was it not rather a 772 ?
