Square D FSG 2 Pressure Switch

Pressure switches are used in nearly all systems with under pressure fluids. They automatically control the energy levels by acting on the feeding of the motor-pumps.Pratically they switch on and off the electric pump according to the pressure. They are calibrated beforehand to the standard opening and closing pressure of the contacts, but they can be calibrated to diverse pressures by means of an adjustment device.
