Dan:

I have separate switches for high and low boost on my Legacy.  I use
high boost for 5 seconds before starting; I don't use low boost at
present.  I would consider separate switches with the high boost switch
being a "momentary on" type if I were doing my panel again.

Subject: [LML] Boost switch

With the current discussion about the recent accident, I am curious
what others have done with the fuel boost pump switch.  It seems like
the options  are for separate switches for high and low, a 3 way Low -
Off - High and with a 3 way with the High being momentary.  I think I
am favoring the  later with the thinking that the high boost is really
only needed during start for engine prime and as Skip stated this
precludes leaving the high boost on.
Other thoughts?  Does this apply to the IO-550 as well?
Do any of you flying, use the high boost for anything else.  In an
emergency would you use high or low boost or try both?

I am doing a IO-550 in a Legacy.
