Can this switch be set up with a manual reset or do you have a switch with this ability, I am looking for the switch to shut off power when pressure rises to 180 PSIG. The switch would be used in Anhydrous Ammonia service and located outdoors.

Asked by: stupid question to answer
Thank you for your inquiry, The PSW-243 does not have the ability to do a manual reset, this unit is designed for harsh environments (Class I, Division 2).
