Hello.
I have here a home appliance. It's a portable hoover. Not sure this is the correct name for the following appliance:
The problem with it is that all of a sudden, we couldn't stop the appliance. It was working even when we turned it off on the switch (3 states switch).
So, I disassembled and found a floating wire (black wire) and I soldered it to where it should be.
I'll share a few links with pictures I took from the "thing" this black wire should be connected to.

I have no idea what this is, but this is not accessible from the outside of the appliance. It was inside the case. I can only think this may be some sort of protection, because the metal plate of the red wire seems to be some sort of magnetic switch, as it is in a V shape and it's making contact with the plate of the black wire.
I'll try to represent what I see. If the '|' is the black wire plate and these 2 representations are the metal plate of the red wire "\ |" and " ||", they can combine themselves as position 1: |\ | and position 2 | || . Not sure you guys know what I mean.
Anyway, the reason I created this post is because, sometimes when I connect the charger to the appliance, the motor inside seems to want to start spinning, but it doesn't and it keeps doing this weird sound as if it is trying to start spinning. Other times, I connect the charger and nothing happens but a red led lighting up telling it's in charge mode.
When I connect the charger to the appliance and the motor tries to spin, I can feel at least one component going quite hot, so there is a short either in this component or somewhere else. But this only happens if the motor tries to spin.
The component shows only this reference: 4403 CT7A2 and I couldn't find anything like this.
I have a pic too:
I have removed this component and soldered it back to place, just in case it could be some pin shorted. But no luck.
I might also have to ask help with the switch because it may also be not in the best conditions, but that will be for later, if I have luck with this component!
