AS16 is a low-pressure cutout switch — it turns the pump off on a 10 PSI drop in pressure. If a motor exceeds the ratings above, wire the switch to the pilot circuit of a magnetic starter or contactor.

⚠ Before You Order

Match the pressure setting to your tank pre-charge and system design (tank pre-charge is typically 2 PSI below cut-in). Higher-HP pumps may require AS10. Wire per local and National Electrical Code requirements.
