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, 🗦 TAK 🗧 , 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.
