Bill,
While one could expect the gear to not come down, there are many imbalances
while the gear is up - gravity and the nose gear gas spring come to mind - this
should relieve the pressure as soon as the dump valve is selected.
On the other hand, the gear down and locked is in a very stable
condition - so one should only need such a switch for gear retraction.

Angier,
I think that you'd need 2 push buttons, one for each
pressure switch.
Wiring both pressure switches to one push button would be
trying to run
the pump in both directions at once.

So, would not the
simple solution be to wire both sides of each
pressure switch to a
momentary push button switch?
I have gages installed and so can observe the
hi/lo pressures. A push
of the momentary switch should start the
pump.
