the.com/kill switch
The button that trusts nobody, including the person who built the thing.
means A single switch or mechanism that instantly shuts down a machine, process, or system in an emergency, overriding everything else it's doing.
from Straightforward compound of 'kill' (to stop/end) and 'switch' (a control mechanism), emerging with industrial and later automotive machinery in the 20th century — the term shows up with things like engines, record players, and factory equipment that needed an instant, no-questions-asked way to cut power. No hidden backstory here: it kills, it's a switch, the plainness is the point.
