Rated 5.0 out of 5.0 by Square D works for me. The installation was easy,but getting to the old one was something else. I've used Square D produces in the pass and have had no problems with them. The old pressure switch was Square D, made in the USA, and it was over 24 years old. Time to retire the old work horse. The replacement is built as good as the old one and the price is cheap.

Rated 4.0 out of 5.0 by Good Product SqD products in general have always been dependable. These pressure switches are no exception. Its replacing another one so poorly made the plastic mtg block was melting under normal use after 6 months. I have every confidance in SqD. September 13, 2011
