Scheppach TKU switch broken

[woodiedonald]

Hi, could anyone help me with this?

Recently the switch on the Scheppach TKU site saw a friend has seems to have stopped working, the saw turns on but you need to hold down the start button to keep it running, it cuts out as soon as your finger comes off the button.

Has anyone had this problem before and any ideas on how to go about fixing it?

Cheers

Dust trapped in it at a guess. I have heard of similar problems on various saws- stripping/cleaning it out often solves it.

Either muck inside, a bad connection or the relay is fubar.
