Review on Rule 37A SuperSwitch Switch Moisture by David Shah

New mercury free super switch may be good for the environment but not so good for my (nearly sunken boat). I have been using Rule switches and pumps for over 25 years and I can tell you they are THE BEST. After more than 10 years of service, my mercury superswitch failed. I replaced it with a new style, 5/10. After only 1 year the switch broke while I was on vacation in the country. It was raining heavily and when I got back I found my boat had over 12 inches of water in my hold. The new style change didn't work. I called Rule and they were very nice and sent another switch but said it would take 3-4 weeks to ship. So I ordered another one from Revain. So far so good and now I have a spare switch. 06/13/2013 UPDATE! The switch I replaced failed again (in heavy rain of course), Rule no longer has warranty information and I was unable to contact them. Old phone numbers are disabled, impossible to get through online. I bought another one hoping they found the problem and updated the switch.
