Full StarFull StarFull StarFull StarFull StarWorks fine
by Patrick from Panama City, Florida on December 03, 2012
I had an intermittent light switch I needed to replace so I replaced the bilge pump switch and the bait well switch at the same time. The local boat store didn’t have any and even said they never even heard of a rotary switch on a boat. I found you guys on line. A week later I had new switches. All three switches were drop in replacements.

by William from Vacaville, California on September 08, 2015
After seeing the plastic construction of this switch, I'll be buying a metal switch to replace this one. I should have payed a little more for the peace of mind on the water.
