Our industrial/commercial grade pressure proving switches are made from a die cast aluminum body and contain no plastic or stamped tin parts. They are made to last. They will not crumble, crack, dent or corrode. It is not uncommon for these switches to be operational for 40 years.

Our switches are used to detect small air pressures, vacuums or changes in air pressure. Can be used to prove airflow in burners, detect dirty air filters, verify duct pressures among many other applications.

Custom calibration and configuration is available for free. Pricing is very competitive for volume purchases. Use in applications where a switch failure is not desired. Made in USA. UL and CSA certifications are available. Call us for your special needs. If you need special pricing, email us at sales@beccontrols.com
