One problem with a mechanical float switch is that the amount of water needed to activate the switch may exceed the amount you would tolerate swashing around in the bilges. Another problem is that conventional mechanical switches are well-known for maintenance issues (= failure when you need one the most). If you are committed to this type of pump activation, you might prefer a Water Witch ( http://www.waterwitchinc.com/product_sheet/bilge_switchsheet.html ), which uses a contact-free system for activating the pump. Buddies out here who use these in their power boat bilges swear by them, after having had one or more mechanical float switches fail, sometimes in catastrophic situations. The simplest model should work for a kayak, and only draws 6 mA at rest. -- Dave Kruger Astoria, OR *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
