Hi Psubbers,
I'm looking for a vacuum switch that operates a
pneumatic valve & runs off 12 volts.(valve switch combo)
I'm using Phils bellows add system for life support
but want to replace the bellows & regulator with a
vacuum switch that opens a valve in the
oxygen system when it senses a drop in cabin pressure.
I've found something that may do, the Norgren 18 D
series 0880100000000000, but aren't confident enough to order it.
I have a solenoid valve that I could plumb in to
the O2 line & have operating from a vacuum switch, so
alternatively
I'm looking for a vacuum switch that operates off
12 volts. I have vague recollections of this being discussed ages ago
&
a source being offered.
Any suggestions appreciated.
Regards Alan
