Switch, Duct Pressure Review

This was a good product, but the cost seemed a bit steep (I paid around $50 for it). Also, beware: for my application it turned out to be unusable. I had it installed in the trunk of a central heating unit (very close to the main blower) to control some booster fans. As it turned out, the several booster fans were so powerful that they sucked the air faster than the main blower could push it; As soon as the booster fans came on they created negative-pressure in the duct, so the pressure switch would turn off. Then the positive pressure from the main blower would turn it back on again (on, off, on, off, and so on). I wound up abandoning the pressure switch and just having the boosters wired directly with the main blower. It would have been nice if the pressure/sensitivity was adjustable, but the product does work as designed so I can't complain.
