Our differential vacuum switch products are sensitive single pole switches that can be used as pressure or vacuum switches, or as differential pressure switches.

Differential vacuum switches monitor the difference between two systems. Sensing a low range of pressure, these single pole single throw differential pressure switches monitor air pressure in sensitive environments and sense when low pressure occurs. Sensitive differential switches are weatherproof and explosion proof can be factory set or adjustable simplified calibration.

Sensitive pressure, vacuum or differential switching. These sensitive single pole switches can be used as pressure or vacuum switches, or as differential pressure switches. The switch can respond to rapid pulsing and the gold plated silver contacts will handle low level switching currents. Adjustable air bleeds can be supplied on either side of the diaphragm for pulse sensing applications involving safe edges or bellows.
