No, I've never really been fascinated by this type of dead switches. I have always considered the circuits to be necessary, but not particularly intelligent. The relay does exactly that, which the switch does as well. Only with the so-called tipping links do the switches come alive. This can be seen, in real life, when switching on the stair-well lighting in a block of flats.

Suddenly, the same switching function can have different effects. After a while, the switching function is also automatically cancelled. The light, apparently, goes out all by itself. In this case, for the first time, one speaks of a storage, because also after releasing the light-button, the function still remains. One bit remains (at least for a time), it's still a long road to the computer.

Should a latching-stage also be described as a Flipflop, then, in this case, it concerns a T-Flip-flop, derived from the word 'toggle' (to switch back and forth). Should there be a switch each for switching on (setting), and for switching off (resetting), this is described as an RS-Flip-flop.

If the Set input is operated, this High state is taken over from the output and will not be reversed if the Set input goes low again. This also happens when the Reset input goes at High and the output at High. If the light goes out by itself, this would correspond to a mono-stable latching stage, if it stays on until it is switched off, it is called bi-stable.

A good example of a mono-stable flip-flop, is the burglar alarm in the car. Just imagine if it would howl the whole night long, keeping all the neighbours awake. No, it switches itself off after 15 sec. (feels like 15 mins.), without any intervention. But there is still another form of flip-flop without saving. So you can with one-off press a button the light switch on and switch off, when pressed again. The also has a storage, because the switched on state remains first of all, even when the button is first released. 10/13
