Dyson DC04 Power cable and switch removal

[GBW]

My mains lead is pulling out of the cord grip below the push switch. I obviously need to remove the switch but can't see how it is held in. Can anyone tell me where to insert a screw driver to snap the switch holder out please?
Many thanks.

Thin, bent, screwdriver down the side of the on/off button. You should see a tiny slot where it goes in. Waggle it and the button should pop out.

Hello, and thanks for your help.
I guess this is the slot down the side of the button itself (on the same side as the handle)? Very small and about an inch deep?
Bloody Dysons - still won't come away. Thought I'd better just check before I lean on it a bit harder. Tried welding wire as that was all I had that was thin enough and then filed a flat in case it needed a "lead in".

They are a pain to get off. Dyson engineers have a special tool which is basically a terminal screwdriver with a bend in the shaft. Insert the flat of the blade and lean in toward handle and it pushes the retaining clip in.

Thank you Sleepyhead.
Have managed it using a small allen key with an extra bend.
Cable outer had cracked and separated so repair is straightforward. However to have left it would have been creating a substantial safety risk.
But what a so and so to get that blooming button out!
