I can't say many pros or cons to these switches. They are what they are. Pushbutton with touch contact "closer". They come with colored lenses but I would be happier if they came with 5 sets of lenses in different colors so we can choose the lens color or customize the lens color depending on the switch application. . Otherwise, we offer a set of interchangeable color lenses, so we can choose the color to buy by ourselves. The downside is that multiple kits have to be purchased to customize the lenses for the number of switches required. this. If two switches need to be the same color, you need to buy two packs of switches to get a set of corresponding color switches. It would be nice to be able to buy or provide multiple interchangeable lenses.
