Dyson DC04 Switch/Lead
 

After seeing the answer to this many times my lead has now failed. Dyson
want £50 to send an engineer, yeah right! I can see the slot people talk
about for removing but has anybody any info on what to use to get down the
slot? I have tried a small jewellers driver and some jet cleaners but don't
know if they are reaching the 'locking tab'. What length does the implement
need to be and am I likely to have anything in my garage suitable?

Many ythanks

John
