SR-500 Stingl Switch
(Safety Vacuum Release System)
The Model SR-500 is a Safety Vacuum Release System (SVRS) which works by monitoring the vacuum on the influent side of the pool or spa pump. When a blockage occurs in the main drain or skimmers, a sudden rise in vacuum will cause the SR-500 to shut down pump operations and activate an audible alarm. The pump will remain off with the alarm sounding until manually reset.
