A safety lock device of an instrument switch is provided to remove inconvenience of a driver when the safety lock device is turned off, by recovering a switch knob to an off state in order for a contact point state of the switch body to be turned off as a safety knob is unlocked by applying pressure to the switch knob. A safety knob(200) is installed on the surface of an instrument switch knob(100). A safety bar(210) is formed on the bottom of the safety knob in a body. A safety lock bar(300) has a top part connected to a bottom part of the safety bar to rotate around a hinge(600). A hooking protrusion(410) contacts with the safety lock bar to rotate around the hinge.
