Why did my Dyson DC04 switch spark, then motor died?

The problem is probably not the switch but a fault dysons suffer on a regular basis , the cable blows at the point it enters the machine. check to see if there is a small hole in the cable at the entry point to the machine . The cable bends at this point when in use and it becomes a weak spot. If you loop the cabe in your hand when using the machine , it will prevent the problem in future . (see replacing a dyson dco4 switch to remove the cable for repair )
