manual release
Physical override mechanism
Manual release is a mechanism that allows something to be disengaged or opened by hand rather than automatically or electronically.
Emergency exits have manual releases for when power fails.
The term appears in contexts from aircraft landing gear to seat belts to industrial equipment: Pull the manual release if the automatic system jams.
In photography, a manual release is a cable or remote trigger for the shutter.
