Hi,
as per following schematic I tested On/OFF switch. I was able to turn it on and somehow I understand "on" functionality but regarding "off" function never worked for me and I would like if someone can explain it and there is not a problem in schematic overall. I also measured voltage at certain points:
1 - after connected to power
2 - after first pressing button
3 - after second pressing button
I used original schematic but I used different MOSFETs
Range of Vgs for MOSFETs: Q1, Q3 VBF2355 ((-1.4) - (-2.5)), Q2 P140NF75 (2-4V).
Thx
