Buckling Spring Key Switch

The Buckling Spring Key Switch is famously used in IBM Model M keyboard
You press the key, the spring compresses, then at some point, it can't
take it anymore,
, it buckles, giving up all resistance.
That means you get a clean precise feel when the key is activated.
A drawback is that it is very loud. The sound came from the spring hitting
the key's inner wall. It's crispy and precise.
