Water Witch 12v Electronic Bilge Pump Switch Model # 230, 20 Amp

Requires no adjustments and works in an oily bilge. This eliminates the chance of your battery dying or your pump burning out because of a failed mechanical switch. Water need only touch the lower sensor for 6-8 seconds to activate the switch. The delay eliminates pump stutter and once water has left the sensor, the switch continues to run the pump an additional 14 seconds to clear the output hose. Temperature, humidity or electrical noise will not affect this switch, nor will the 230 interfere with other electronics. FEATURES + BENEFITS • No moving parts; no electrolysis • Impermeable to all bilge substances • Activates when water touches lower sensor • Will not interfere with other electronics • Only works in saltwater.
