A pull retainer emergency safety switch includes a plastic housing and a switch module, wherein, the plastic housing has a push block device and a pull retainer piece has a ring retainer. The ring retainer abuts on a rotating handle configured in an upper portion of the push block device, and causes an underside of the rotating handle to abut on a triangular push block, and a bottom surface of the triangular push block is utilized to abut on a top surface of another triangular push block, thereby enabling a side surface of the second triangular push block to abut upon a push button of the switch module. When pulling on the pull retainer pieces the rotating handle with an anticlockwise rotating force produced that actuates the triangular push block and enables a horizontal displacement thereby pressing the switch module to actualize rapid cutting off of power supply.
