Well built!
Working great in my RV. Very well built. Makes it easy to stop voltage drain. Will also help in diagnosing the voltage drain.

It's backwards
Locking orientation is backwards. Looks robust...but it is of no use to me. Why lock it in the on position??? Poor quality control
User
Great switch
Great product.100% recommended
User
Works very good, but there must be a dropout in translation.
The lockout feature is backwards, I just drilled a new locating hole so it can be locked in the off position. Not a huge deal, but it is an issue.
