Jun 29, 2023 at 20:50 comment added Danster Yeah, your idea is not bad, but i want to find easier and safer what to do that, like at MCU1 short some pin, like in this post with momentary switch…

Jun 29, 2023 at 19:16 comment added Simon B @Danster I'll update the answer.
Jun 29, 2023 at 18:38 comment added Danster contact spring (if you meant touch button) has no voltage or i am not right? I tryied to touch it without cover, and i didn’t feel anything, so i don’t know. About your idea i don’t know what you think that i have to do.
