My pillar drill started not turning on propery. Each time I pressed the green button it would only go while I had finger on button.
I would have to try it up to 10 times before it finally stayed on.
No problem I thought, I would change the green/red buttoned on/off switch.
I took it apart and there's a weird (to me) strange part next to the switch (see photos, 1 of side, one of bottom and two looking down the top, one with flash the other without).
The hole in the middle of the top down view is for the screw that holds it next to the on/off switch. While it looks metal from the pics, it's plastic.
The two outs from the on/off switch go to the motor.
The neutral from the mains go to the in on the on/off switch.
The live from the mains go to the weird bit photoed.
There is a safety switch in the lid with two wires, one goes to the weird bit, the other goes to the in on the on/off switch.
I've made a quick diagram showing what I mean
I can understand whats happening easily enough, if the lids open, the on/off switch doesn't get any current.
However, if I have the lid open, pressing the green button does nothing as I would expect.
Closing it, and I'm back to trying about 10 times before the on/off switch works. hence the safety switch in the lid is working fine.
If I bypass the weird bit/lid switch completely, and simply have both the mains on the IN side of the of the on/off switch it works 100% fine, every time I press the green button it starts properly and stays running.
As soon as I go back to using the weird bit, it takes about 10 times for the start to remain on.
My conclusion is, the weird bit is faulty, but what is it?
Happy to bypass it, can't be any more dangerous than my old metal lathe is, but if it's easy to get, will do it properly.
many thanks
