Attwood Automatic Float Switch 4202-1
The Automatic Float Switch converts any bilge pump that draws 12 amps at 12 VDC or 6 amps at 24 VDC or less to fully automatic operation. It features a compact, low-profile design that mounts on any surface from horizontal up to a 24 degree angle. No large voltage drop which reduces bilge pump output like some reed switch designs. Incorporates a reliable and affordable mechanical switch that actuates pump motor at 2 inch water level. Wire leads do not flex or hinge with the float as on some competitive models. Contains no mercury.
