I used this switch to replace the same switch on my 2 battery travel trailer. Very easy to install and works great, turns very smooth. I think the old one was atleast 20 years old. Very satisfied.
Old switch gave low output voltage on position number one. Switch was installed in 2007 and boat is used year around, so the switch has seen many successful cycles. New switch is the exact same switch, is well made and the internal break and make parts are very durable.
Nice product and worked as expected. Installation was easy. Just wish they would have included the 4 mounting screws, the positive common cable (red) and saved me trip to the hardware store for these items.
