Their basic components are the housing, mounting kit with plunger, compression spring, adjusting element and micro switch. If the pressure to be monitored is below the set value, operate the micro switch. The pressure to be monitored is transmitted to the plunger through the orifice. The plunger is supported by the spring seat and overcomes the changing force of the compression spring. The spring seat transmits the movement of the plunger to the micro-switch and releases the pressure of the latter when the setting pressure is reached. This will open or close the circuit, depending on the circuit Settings. The mechanical front block of the spring seat can protect the micro switch from mechanical damage and prevent the compression of the spring under the condition of sudden decrease of pressure and over pressure. Note: to extend the service life, the pressure switch should be installed with small vibration to protect it from hydraulic impact.
