Replacement Square D Pressure Switch, UnloadFriday, September 28, 2012
The product is an exact replacement for one smashed on a compressor - if it works as well as it's predecessor I will be very happy. Not tried yet.
That it was still available - my compressor is 10 years old.
Nothing, just keep doing what you're doing.
