How does the switch on my bike light work?

Question

I have an LED headlight on my bike. If I press the switch once it lights up.
If I press it again, it starts flashing - when I press it again it goes off.

How does that switch work? Does it use transistors in a speciall circuit - or is it something else?

Answer 1

There will be a tiny chip that has the logic to switch between modes when the switch is pressed. The switch itself will be nothing special.

Answer 2

the reason why it does that is what is generally known as a flip flop circuit,controlled by a switching transister.
