awful, just plane awful, this is a terrible way to make a lag switch, look at my pic, that is a awesome lag switch, i use a push button so push on for lag push off to un-lag and it is on the floor so i push it with my foot, who the hell would make it with a light switch, garbage, u should really take it down cuz this is sooo bad. im not "flamming" but really dude, bad. i can see that ur trying to help ppl who dont know how to make one, but for the ppl that want to make one, DONT USE A LIGHT SWITCH, go to radio shack and buy ur self a push button, a lot easier.
