A monostable has one stable state.
The stable state of a 555 in that configuration is with its output low. It will stay low until it receives a trigger, upon which it produces one high output pulse.
An astable has no stable states. The states change continuously.
In a 555 that means the output alternates between low and high. The 555 will start doing this as soon as power is applied to it.
The idea here is to develop a vocabulary of switches.
Is it responsive?
Does it require human or dog interaction?
Does your switch have multiple outcomes?
Does your switch trigger a series of events or actions?
SCALE and CONTEXT of the switch!
Necessary to draw a diagram or a schematic.
When the fan is switched on, it disconnects the switch by blowing the aluminium foil apart which in turn switches off the fan. When the fan is switched off, the aluminium foil comes back and completes the circuits, thus making a loop within itself.
