Features:
This is an adjustable pressure switch with a normally closed (NC) configuration.
It can be adjusted using a hex key to set the pressure range from 15 psi to 140 psi.
A relay or solenoid is required to handle the load and protect the switch contacts.
The switch operates in an “Often shut down” mode by default, where the contacts are closed.
To set a specific pressure value, the contacts are disconnected, and power is supplied to the line.
