Newbie - help me identify part, please!

Good Morning, I am fixing my bike light and looking for some guidance / knowledge of what this switch is called. (please see the images below) It's the aluminium coloured one in the middle. I've seen it acts like a popper switch, with a rubber switch operating it. It's suffered damage and needs replacing but have no clue what to search for to find one!

Any help would be appreciated.

Seasons greetings!
Henri

It is called a "dome switch" or "metal dome switch" or "tactile dome switch". It is a little piece of stamped and hardened steel gives it a quick spring click when enough force is applied.

In the Uk tactile switch is what I'd call that.
Search through some old e waste ypu might be able to find something, they are common.

Thank you for the information! Useful
