PURPOSE: A switch knob is provided to maintain the switch knob at the stable state, while allowing for ease of attachment/detachment of the switch knob. CONSTITUTION: A switch knob(300) comprises a main body(310); an insertion groove(320) formed at the main body, and which permits a switch rod(210) with a through hole(211) to be inserted into the insertion groove; a support member(400) arranged in the insertion groove in such a manner that the support member has a position changeable from one side of the interior of the insertion groove to the other side of the interior of the insertion groove; and a fixed protrusion(420) projected toward the switch rod and coupled into the through hole of the switch rod when the switch rod is inserted into the insertion groove and drives the support member in one direction.
