As a newbie, Switch section is designed according to my knowledge. Please let me know the review for this section.
Switch is connected with the microcontroller. I have tried to protect microcontroller from positive & negative spike. The distance of switch from microcontroller is approx. 6 Inches. Here Vcc is 3.3V & microcontroller also works on 3.3V.
The schematic for the switch section is attached.
