The pressure switches are used in nearly all systems where there are fluids under pressure. They automatically control the energy levels by acting on the feeding of the motor-pumps. Pressure switches 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 and the values that can be obtained are indicated for each one product.
