SKU: BG-SWA Category: GTIN: 851282008112


The BG-SWA (Solid-State Bilge Pump Switch with High Water Alarm) is a highly reliable bilge pump switch that is the ideal replacement for unreliable mechanical float switches with an integrated high water alarm. The BG-SWA uses two integrated sensors to detect liquid in the bilge while reliably activating the bilge pump. Having no moving parts that can be jammed or damaged, the solid-state BG-SWA is built to outlast all the mechanical float switches on the market today while alerting you of water presence in your bilge. The BG-SWA is CE and ISO 8846 Marine Ignition Protection Certified, tested to ABYC-1500 standards. Patented technology.
