Just had a thought about the gentleman who lost
pressurization over the Sierras.
Although the door seal switch tested fine after
this event, they way I have interpreted all the posts is that somehow,
the door seal switch had moved during flight.
Has anyone given any thought to replacing the
toggle switch provided with the kit for either a guarded toggle switch, or at
least the one that requires you to pull up on the switch before it will
move?
Just a thought

The short answer is yes I looked at all those options. The Switch is not
electrical, it is an Air switch that routes the air to the Seal (on) or to
a dead end (off). When the pressure builds to the set point the pump stops in
either position. So, I looked up the manufacture of the air switch and read the
specs., looked for covered switch options and there were none. My switch met or
exceeded the detent load that they spec. and really is quit hard to flip from
the ON position when it is pressurized. About twice as hard as when the
seal is not pressurized. So, I'm left with designing my own and I haven't come
up with anything that makes sense yet. In the mean time, I just double check
that it is on all the way.
Thanks for the thought,
