Seems good, but fragile...
by Joseph from Woonsocket, Rhode Island on October 19, 2016
I am going to use this as a new shift switch for a '71 Johnson Hydro-Electric. While installing it, connecting the female blades to the male blades on the switch was no problem. However, I had to remove one and it was difficult so I had to use mild force andthe male leg on the switch broke so now it's only a 1 position switch. Off and 2On... Ordered another one and will be careful. This time was my fault entirely...

Works 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.
