Features:
Pressure switches are utilized to sense variations in pressure within liquids or
compressed gas substances. Set points may be established at two distinct levels to
either activate or deactivate the switch.
Protects equipment from harm when pressure levels are excessively high or
low, thereby guaranteeing safety for both the system and individuals.

Contains two contacts: 1-4: NO (normally open) and 1-2: NC (normally
closed).
Upon reaching the limit, the contacts will their condition and respond.
