This will switch off the printer automatically when the print is completed.
The pusher is attached under the bed and will come to push a switch when the bed is coming forward at the end of the print.
The extra switch will need to be connected in parallel with the existing switch of the power supply.
When you want to use that functionality, switch off the power supply switch on turn on the one you have just added
The author remixed this model.
Adapted to work on SV06 (original is for SV06 + ) by adding a switch to the side and lowering down the arm from the existing pusher
