EDIT: Original problem was to make button presses momentary, but looks like it is not needed.
Hi all! This is my first post here. I'm total newbie and just starting electronics hobby.
Also english is not my native language and I have poor vocabulary.
My first project is to make my cheap soldering station more practical for adding auto sleep function.
Soldering station have 3 slot memory bank for tempatures which are selected by separate momentary switches. Looks like it don't have any effect if those switches are holded down.
I have sleep tempature saved to slot 1 and working tempature saved to slot 2.
I already have made simple mod, that when I put iron to holder it closes switch.
So now I need to make it press button 1 when I close circuit and press button 2 when I open it.
There should be short delay for setting work tempature (button 2).
There is 5V across switches.
Like this:
Circuit closed > Press button 1
Circuit opened > Delay 500ms > Press button 2
I think it is easiest to do with relay, but how to add short delay-off?
Or do I just buy cheap "multifunction" relay from China? Looks like function 10 is what I want:
