I have a 12V source, three loads (LEDs), and a common return. I would like to control it with a momentary micro switch, similar to this soft switch circuit: https://www.google.com/patents/US7781920?printsec=drawing
Only I need it to toggle fouir states:
1. off
2. turn on load 1
3. turn on load 1 + 2
4. turn on load 1 + 2 +3
I have seen this type of behaviour in LED headlamps, where you push a button to advance through modes/brightnesses.
Is it possible to create this circuit using common components (transistors, resistors, capacitors etc.)?
