PA-28-200R Landing gear

So you are correct. The gear up switch does not shut the hydraulic power pack off.

Neither do the gear down microswitches as far as I'm aware.

--as an aside, you should watch (listen) for a pump which does not shut off; usually indicates a leak in the system (and will wear out that expensive pump if not repaired). It will stay on to keep the gear (and pressure) up; the gear may stay all the way up, but the pressure will be too low for the pump to shut off.

Then what shuts the pump off at the down limit? My manual shows a pressure switch only in the side of the system that's pressurized when gear is going up.

Then what shuts the pump off at the down limit? My manual shows a pressure switch only in the side of the system that's pressurized when gear is going up.

Three down limit switches will shutoff the pump going down. ~1800 PSI (not up limit switches) will shut the pump off on the way up.
