Hand mixer stuck at highest speed

[pjgfi]

Hello,

Not sure this is even electronics as it seems so basic but my mixer has no more speed variation and always runs at full speed.

I have no idea what could go wrong as this is such a simple device and I suppose it just connects to a different amount of turns in the coil when I move the switch.

Thanks for your help.

If it is the kind that has a triac, this could be shorted?

Thanks for your answer. Can't see any... But it's got a "Turbo" microswitch on the side that could be shorted (how did I miss this?)
