Hi Ken,
Thanks for adding your relay based idea possibilities.
If the OP has only limited electronic experience, very often relays are a practical solution.
working with integrated circuits is all very well, but relays can often be much simpler.
Ken, i have looked at your circuits closely, and they are (of course) correct in their
operation.
They use standard type relays with c/o type contacts.
I was thinking of reed-relays because of their low power requirements,
however, the relays would only be operated a brief period, so maybe standard types are Ok.
Plus with standard types, one can see the operation of the unit, which can be important to
the person making the unit.
I rather like the added contacts on each opposite capacitor, because:
Without them, if the user goes from one position to the other, a couple of times before
leaving it in the position he intends to leave it, then the cap could retain enough charge
during switching to malfuntion.
However the inclusion of these extra contacts ensures that the cap is discharged each time
the switch goes to a choice.
This was something which had me going, namely repeated or accidental switching by the user,
which with one of my earlier circuits would be a problem, so i did not include it.
I dont see from your post which of the circuits is the one you recommend, i assume its the
one with the extra contacts.
I can see no improvement to this circuit, other that simply using a single resistor for
the LEDs, which is hardly worth mentioning.
In fact, i think you have nailed it with that circuit.
