Choosing and fitting
Pressure switches of this type are selected based on the required setting range, switching differential, and maximum working pressure. The medium must be compatible with the switch materials. Installation can be direct on the pressure line or on a flat surface using two screws. Ensure the switch is mounted in the specified operating position to maintain the stated protection class.
Signs of failure
Common failure modes for mechanical pressure switches include leakage, contact welding, or drift in the setpoint. Symptoms may include failure to switch, erratic operation, or the system not responding to pressure changes. Check for physical damage, contamination, and verify the setpoint with a calibrated gauge.
