The solution switch has broken in half. It should be one piece.
Also, I really do not understand this obsession amongst some of the people on here of removing the suppressors from vacuum cleaners. The suppressor is essentially a capacitor and these are in so many appliances that unless you removed them all you are fighting a losing battle. Only the occasional suppressor blows - you hear about it on here sometimes as it makes for something to talk about. On a wet & dry cleaner like this Vax -where water can get into the motor and other parts- I would be much more worried about removing a suppressor and joining the cables together than I would leaving it in, as you can't be sure that water won't get into the join you make.
