Would this information storing circuit work
While you could (as mentioned in comments) use a flip flop, this particular implementation is ripe for a "FET Trick" that would do what you want for quite some time...the capacitor is optional (&amp; needs to be a low-leakage type if used), as the gate capacitance alone will work for quite some time - and I added a reset switch.

It's also easily do-able as a nice olde fashioned relay logic circuit (light-bulb can be LED+ resistor, of course)
