I noticed that Simply Automated has updated their web site.

Have you noticed the holes in the tabs and body of their switches? Having those holes increases the surface of the aluminum, improving heat disipation and increasing the wattage ratings on the switch. These holes, and making the body of the switch out of aluminum allows them to have higher rated switches without adding the wing tabs on the side of the switches. Creative engineering.
