Dyson upright stick type vacuum cleaner (Willen MK15)

Reasonable condition and all original parts, battery ok, but the trigger for on/off does not work. The trigger operates a small button in the handle and if you see picture 2 you will see I drilled a hole in the handle. This gives access to the button and I have been operating the vacuum by poking something narrow into the hole. So, it works, but it is a bit of a fiddle. Maybe you are happy using it like this, or you can improve it, or fix it.
