Pressure Switches for Air
-
(also referred to as a vacuum
switch) |
|
Air pressure switches are associated with gas heaters which incorporate
power venting into their design.
This switch is not intended to operate on air pressure into the switch, they
are intended to activate by air being drawn out of the switch.
Simply put, by sucking air out of the air line running to the switch, the
switch closes.
Most of the
switched listed are pre-set at the factory to accommodate differences in
altitudes for specific heater models.
