Why not just do this the simple, usual way for an

yours: a pair of nice, sealed, heavy duty industrial pushbuttons
marked UP and DOWN, or even a single button with a nice heavy duty
toggle switch similarly marked?
For safety, the buttons on the lift (in the
bucket), are air switches,
with the actual electrical portion down below. I have not seen the
unit, but my father claims there is no more room for another air line in
the boom cable trace, so any more switches would have to be wireless, or
something else.
Personally, I'd be a little leery pushing that button without knowing
which way the lift is going to move when I do...
I think that's why he wants
the minimum complexity (no solid state,
etc.). I agree, there is some risk there, but he is currently happy
with the operation using an unsealed relay, I told him surely there
existing a sealed version of this thing.
Yes, I could happily re-engineer it for him, but just like ill conceived
concepts on a vintage machine, I'm being asked to just make the current
setup work, not create a new setup.
