My electric vac doesn't switch on - Vacuums

You should simply purchase and install a new switch. It's not safe to bypass the switch as when you do, the entire electrical load is placed on the wall prongs when you plug in or unplug the vacuum. Depending on the brand of vacuum, you can easily order parts and replace the switch at a nominal cost.

Check contiuity on the switch.

Replacement parts can be found on amazon, take a look: Amazon com shark vac parts . Have a nice day

There is still other problem beside the fuse. Check the cord, power switch. Often they are the most usable and abuse parts of the vacuum. The cord are often bend, roll over the floor. While the switch
is the almost use before and after the vacuum is used.
Thanks for asking.

I believe this is it
10A 250 VAC
15A 125 VAC
3/4 H.P. 125 250 VAC
They have a list of retailers who sell their products.

Check that the electrical cord if fully inserted in the
wall outlet. See if the vac has a circuit breaker switch
on the electrical plug called a GCFI,or on the vac itself,which probably has tripped. Good luck.

Check the othere end of the switch. You may have a brushes problem in the motor. You will have to check the switch while hot - be careful

it doesn"t have either one if vac won"t turn on its probably a bad switch

I had the same problem with the same model. Turned out to be the thermal fuse on the motor housing, between the switch and the windings. Took it apart and replaced the melted solder with 14 guage copper wire. Works fine! No thermal protection but I don't use it for long at a time anyway. Check the switch for continuity, if good then check the thermal fuse for continuity. If good, it's the motor.

Here is a picture of the dome taken apart, not too hard, take out the 3 screws on top, then the pic should show the rest.
