Pressure & Vacuum Switches – Reliable Solutions for Monitoring and Control
Pressure & Vacuum Switches are electromechanical devices designed to monitor pressure or vacuum levels in a system and trigger an electrical contact when a pre-set value is reached.
They play a critical role in protection, control, and automation—for example: activating pumps, alerting operators to low pressure, shutting down equipment in case of overpressure, or controlling vacuum levels in manufacturing processes.
Modern pressure and vacuum switches offer:
-
High accuracy across various pressure/vacuum ranges
-
Multiple mechanical and electrical connection options
-
Robust housings for demanding environments
-
Long service life with minimal maintenance
