Mechanical pressure switches, also known as hydro- electric pressure monitors, are used to connect or disconnect electric circuits. A pressure switch can serve as a control unit and as an optical or acoustic monitor or indicator. Barksdale pressure switches are chiefly used in hydraulic systems for monitoring minimum pressures, such as protecting pumps from dry operation or as protection for oil lubrication systems. They can also be used for monitoring maximum pressures, such as automatic switch-off or warning device before a pressure relief valve reaches its limit pressure (fig. 1)....

Contact Protection The micro switches (MS) used in the pressure switches are normally suitable for both direct and alternating current operation. Inductive, capacitive and lamp loads may, however, considerably reduce the life span of a micro switch and, under extreme circumstances, even damage Contact Protection The micro switches (MS) used in the pressure switches are normally suitable for both direct and alternating current operation. Inductive, capacitive and lamp loads may, however, considerably reduce the life span of a micro switch and, under extreme circumstances, even damage...
