This switch is very popular.
I just picked one up at West Marine
It's model #43 (3-way lighted switch).
My concern is that when the switch is in the "automatic" mode that the other end of the rocker switch sticks out and could easily be bumped into the "off" position by mistake.
It doesn't seem like a good design.
I haven't installed it yet as I may take back to store.
A rocker switch must be better than a protruding toggle style switch that could easily be broken but I am thinking that Rule
may have fell short in development.
I am puzzled though as it is a popular model.
Sorry I am not near a camera
for a picture.
