apologies if im in the wrong cat. i have a small modelling saw, power is going to the adapter with lights but nothing else!! is there a way to establish if its the motor or switch? the switch has been known to be temperamental at times. any advice would be great as i am not hot on this topic.

You will need a multi meter to take things further.
What is this "Adaptor"
Picture?

Could be the switch , which should be a”NO VOLT” switch , if it is likely the switch coil has burnt out.
Just a thought does the motor start if you hold in the “ON” button , another clue if the motor runs for the problem being a no volt switch.
Possible the speed adaptor again fairly crude devices similar to those found on drills with leads, usual thing on motor for a failure is the field coils or armature assuming it’s a conventional power tool motor with brushes , but when they pack up it’s usually obvious , an induction motor will hum if the capacitor is shot.
Be careful poking around with a meter if your not experienced.

simbarb1, I am not being awkward it's just that it could be a variety of things and without a multi meter, and knowing what to look for, you would be better off buying a complete new modelling saw.
You could try to replace parts, but where do you stop? (Unless you know which part has failed, for which you need..........)

What you're asking is a bit like giving somebody a coloured ball in a dark room, and saying, "What colour is this?"
Make, type of saw, and photos of the saw and adaptor would all help.
As already said, a multimeter is needed to test things.
If the switch has been dodgy then I'd look at that first.

That's a brilliant saying. Duly noted.

Yup.
And the make and model etc.
Might help some other person with the same problem some time.

I wondered if the socket was switched off, thats the extent of my electrical knowledge
