I've now started work on the same, and found these listed on a site, which I thought would be great, as they have a mounting screw.

But I couldn't find them anywhere in the US, and if you get them from Alpha Therm, you have to buy 100.

But then found these, on Aliexpress, which are also posted on Amazon https://www.amazon.com/dp/B07KQFWGPX?th=1 which I am going to give a try.

Same thing here from Aliexpress, much cheaper.

I have installed my thermal switch like this:
2 M3 holes drilled without going through and using M3X4mm capscrews.
A small amount of thermal paste was used between the switch and the bed plate to ensure good thermal transfer.

Do not omit to use heatshrink or other contact protection. This is LIVE current.

Hello,
this type of switch changes from on to off when the temperature is higher than for example 150°C. But when the themperature is under 150°C switch changes to on again. So it is no real fuse. It is just another switch than the on in the Controler Board.

To be aware of this issue i use the thermal switch with a manual rest function. Just take a look here: https://www.amazon.de/gp/product/B00GLR41D8/

So if you use this one, you have to switch it on manually after a shut off. That is normally the best way, because there must be a reason, why the bed goes over 150°C, to switch it on without any check sounds dangerous to mee.

Just my 2 cent.

Best Regards
Paul
