There is a plastic guard over the switch that enables you to turn it on and it will stay in that position. I use it this way in my router table, with the router plugged into a switch box.
If you are using it in a router table, the only time you will have to reach under and turn it off, is when you want to extend the collet up thru the table to change bits. When the trigger is held in the on position, there is a safety device that will not let you extend the bit all the way to the "locked" position. This prevents you from accidentally turning the router on with the shaft locked.
I've had my Triton for about a year, and I love it.
