A power switch is provided to reduce costs and enhance convenience of assembly by integrally forming an elastic member without using a separate spring. A power switch(100) includes a switch body(102), a center boss(120), an elastic rib(140), a fixing hook(130), and a safety rod(150). The switch body is exposed to the outside of a mask. The center boss is extended to the mask from a center of an inner surface of the switch body. The elastic rib is extended from an edge of the inner surface of the switch body. The fixing hook is extended from the elastic rib to be inserted into the mask. The safety rod is extended from the edge of the inner surface of the switch body and shorter than the fixing hook.
