esp32 analog input protection

This is my setup in progress for protecting the pins from overvoltage. i would be happy for corrections.

target is that the LED does not get more that 3.3v (representing an analog in of a esp32) , the current sensor represents a fuse that should snap on failture, the source represents a 10A/1V current  sensor.

Looks like it doesn't work. I suggest you put in a switch so you can play with 3.3 and 5V intuitively.

in the new review i applied a more realistic measurement. my biggest problem ist currently that the mock for the esp analog input, the led, is not a good representive. also im unsure if the replacement for the TRIAC is correctly working. at last im missing a good way to mock a fuse, the current sensor. next would be the rework of the analog input mock of the esp32. having a more realistic mock might yield a better insight. Changelog: added the requested switches.
