Rule 35A Marine Rule-A-Matic Switch (Mercury Free)

I put it into the bilge of my boat and it works perfectly well. Thank you.

This device is top of the line, at least that is my experience.Though recently I had some problems when at the same time a 2000 GPH pump failed within two months of use even though it has a four years warranty. Amazon Rep told me that I would need to contact the manufacturer because my time warranty through Amazon would be only 30 days and from then on...I would need to contact the manufacturer. ( somewhere in China ) I understand Amazon policy, but honestly I expected more from this Co. And then it occurred that a cheap float switch failed 48 hours after installation. But it happens that the cost of installation is at least three times the cost of the device. So, I decided to go for RULE....to be on the safe side. This is my recommendation. to whoever needsto replace a damaged float switch that are always located as deep and unaccesible as the boat builder could install them....

Bought this to replace my existing float switch. Easy switch and wiring was easy.

Perfect replacement for a 30 year old Rule in my sailboat.

Everything was excellent

added to my tracker 170 - this was compact enough to fit in the very small area near the pump. Good quality wire and seems solid so hopefully will last awhile

My 1998 16’ Lund is a real leaker. After about 4 hours the water would start coming up to the floor. This required me to remember to turn on the bilge pump every so often. If I got preoccupied sometimes I’d forget creating extra weight in the boat. I was usually reminded when the bow trolling motor would surface and make a bunch of noise.Installing this switch has taken that out of the equation. It kicks on every half hour or so now. I bypassed the switch it was hooked to and tied it into the power going directly to my battery with a fused line. I know my Lund has a double hull but I really didn’t want to drill into it. I had a 1” thick piece of HDPE polyeurethane that I cut a block out of and screwed it to that, then glued it to the floor. Gorilla glue or a construction adhesive will work, I used a silicone based adhesive I had laying around. This also elevated it up just a bit from the pump so it will for sure shut off. If the float can’t drop down low enough it won’t shut off. If the float is at the same level as the highest point of the intake on your pump, this may happen.Now I don’t leave a trail of water to my house when I trailer my boat home from the river. The big advantage is I can leave it on a dock at a resort or cabin overnight or longer without worrying about finding it on the bottom in the morning. It also gets rid of rainwater as needed.

Good price. Works as expected.

As superb, quality float switch as is to be expected from Rule.

Adquirí éste flotador para reemplazar el rule anterior que duró casi 3 años en una embarcación de 25 pies sin lona para lluvias, espero salga igual de duradero!!

Funcionamiento y diseño perfecto, precio elevadisimo.
