If you don't have a value specified, it will stay on all the time. Probably, you don't want that.
The other point is you might want to make some type of stop at the right position so the servo can only travel so far. Then you can tell the servo to go slightly past that stop and it will be pressing hard and not twitching. I also made my probe such that when it is pressing on the bed, the probe gets pressed a little bit against the stop. That way the repeatability of the measurements is better.
