A Dyson DC35 with a broken switch - The easiest way to replace it... 

awesome video. thankfully, that little metal tab on the switch on mine didn't break, but I just had to bend it out some. now I no longer needed a death pull on the trigger and just a gentle squeeze. just like new now!

To remove the motor cover with zero damage, once you remove the screw, slide some guitar pics (iPhone repair kit ones work great) up and start wedging it apart. Eventually the sides pop and you can pull off the cover.

Great tutorial Sam , love repairing broken things 👍👍

For anyone in the future who comes across this useful video when trying to find a solution: A solution I have found that worked for this exact same issue; where the metal tab on the switch snaps, is to drop into the void behind the trigger, where the broken off tab would be something solid. I used an appropriate sized nut. I put it in loose but you could glue it to the back of the trigger if you can get in there with your glue, then place the nut or similar on top. If you don't glue it still works fine but there is a little rattle of the loose nut while using the Dyson. This solution does mean there is less travel in the trigger and it no longer has that spring like feel to the trigger as rather than a tab that flexes you have a rigid nut or similar in the gap but it was a cheap and easy solution to get the Dyson back working. I hope this helps people.

I bought one of these secondhand. 20 quid the guy could only get it to work for 5 seconds before it cut out. He had been onto Dyson and had 3 motor bodies as well. Anyway I bought a non genuine battery for it for a tenner and its still going two years later and it has spares. They make for excellent car vacuums.

Can you make adaptor to use makita battery on this?

my issue is the max button on my d35 is stuck in the on position. is there a way to fix that? all the videos i see ignore that issue and head straight for the motr or trigger

Expensive junk really
