I'm new to electronics design and I'm trying to learn how to design a particular circuit. The functionality I'm looking for is perhaps best described as a "latching" action from component B in response to quick off-on actuation of a simple switch, the primary function of which is a simple toggle to component A.
To clarify, let me put it another way:
I have a simple SPST switch that controls component A. Sometimes when A is active, I want B to be active also. B will never be active unless A is also active.
I would like to control B's state with the same switch as A, but I want B's response to the switch to be based on a particular type of actuation: B should turn on when the user turns A off then back on quickly. We could say that this quick flip "latches" B to A.
Continuing with both A and B on, the user can unlatch B from A by again flipping the switch off then back on quickly. When doing so, the initial "off" turns both A and B off, and the following quick "on" brings back only A.
I have been doing some reading and have come up with what I'm sure is quite a hodge-podge of ideas. The main elements are:
Here is a diagram:
My questions are multitude, but we'll probably all be happier if we start out basic, as I'm sure there are plenty of things to be said just about the above. Right now, since this is my first post at this forum, I'd like to hear what others think about this approach, specifically the logic and whatnot.
Also, since we'll be crossing bridges, I should mention: Troll if you must, but please have something constructive nestled in the vitriol.
I should also add, I'm down to read and learn. That's actually what I want. So feel free to drop helpful links and other explanations.

I have been doing some reading and have come up with what I'm sure is quite a hodge-podge of ideas. The main elements are:
- Switch
- Timer (555 or ?)
- Comparison component (AND logic)
- Flip-flop
- Second comparison component (same AND logic)
- Relay
