The Water Witch ® 217, 230 or 230-24 submersible electronic bilge pump switch allows boat owners to forever rid themselves of the archaic outdated float switch. Instead of an unreliable and short-lived mechanical float switch, the 230 has no moving parts and requires no adjustments. This eliminates the chance of your battery dying or your pump burning out because of a jammed-on float switch. Temperature, humidity or electrical noise will not effect this switch, nor will it interfere with other electronics. This switch comes with an unprecidented 7 year limed warranty and is in use by both the Canadian and U.S.Coast Guards.
If it's good enough for them,......why not for you?
THE MODEL 230 AND THE MODEL 101 ARE AVAILABLE IN 24V
