I used a regular switch (that even fit the hole of the old switch). It needs to connect the red (AC_L) and blue (COM_L) when switched on.

I then taped the orange (erp count) and yellow (AC_N) cables ends, so they could not make accidental contact.

I removed the PCB.

I also removed the white cable between the old switch and the PCB (pwr zero).

Put the bottom lid back and replace the six screws (making sure to put the shorter one in the right place).
