AUTOMATIC SWITCH

The Attwood electronic automatic switch detects the bilge water level and activates the pump without a mechanical float: it tells splashes, chemicals, mud or foam build-up apart from actual water that needs pumping out on its own, so the pump isn't run through pointless continuous cycles that would shorten its life.

Fully sealed electronics, protected from water and chemicals.

Technical specifications:
- 12V power supply
- Electronic level detection, not a mechanical float
- Distinguishes water from splashes, mud and foam
- Fully sealed electronics
