Schneider Electric's Square D 9016-BSG-1 Vacuum Switch is a diaphragm-actuated control switch in the 9016 family designed to monitor vacuum levels and actuate a circuit when a set threshold is reached. It delivers a vacuum range of 0–30 inches of mercury (inHg) and is rated for up to 600 VAC and 250 VDC, making it suitable for industrial vacuum systems and interlocking or signaling applications. The 9016-BSG-1 designation corresponds to a 1-unit vacuum switch configuration offered by Square D/Schneider Electric, typically used in enclosures rated for NEMA 4, 4X, and 13 environments.
