Description

I am a newbie and would like to create a simple dual control SSR relay that can be operated using a physical button and an I/O pin from microcontroller independently (similar to a stair-case switch).

I dont have any professional knowledge on electronic design so all things in my first project is copy and paste from here/there with little creativity.

I hope this relay will help guy out there in DYI automation and also home eletronic!

Please share your advice on my drawing with thanks.
