The switch that I use to switch off my hobby desk broke again for the second time. The contacts where welded shut. After replacing it again it was time to fix the cause of the issue. To limit the current I used an altered schematic from CircuitsOnline.
After my incident on my safety transformer project where the resistors burned I did not fully trust this circuit. Therefore I have added a thermal protection that switches the output power off when the resistors get too hot.
I build the circuit in a remote controlled socket enclosure. To mount the parts I used some glue and tyraps.
