Excellent product
I use these DP switches on my automatic self-cleaning strainers, and I am very happy with them. They are compact, robust, dependable, sufficiently accurate and economically priced. The product is exactly what the literature says it is!

Is there a reseal kit available for the PSW-184?
Thank you for your inquiry. There are no field repair kits available for the PSW-180 Series pressure switches

IS this differential pressure switch CSA or cUL or does it carry some other Canadian electrical approval?
Thanks for your question, this series doesn't have any of these approvals.

Can you also please email me the wiring schematic for this DP switch. I do not want the audible alarm if that is an option. I do want the 5A 120VAC contacts
@AdrianV Thank you for contacting Omega engineering, I do not have your email to send you the wiring schematic, kindly email pressure@omega.com so that we can reply back to you. That being said it is a simple contact, no contact circuit that opens/ closes when you go above/ below your setpoint. Thank you.
