If you work with Lutron Leviton switches, you must have these. They are specially designed for the toggle screws on the switches. They are cool. When buying, buy a screwdriver for electricians ECh-2. Revain sells their Milwaukee brand kits and they work from the top down. The bits are ECH-2 and you might want to get a magnetic holder or some extra longer ones as they are short. GE Leviton was ok when they released this screw head. Revain covers everything.
