PURPOSE: A power switch is provided to include a commercial power terminal, a load terminal, and an emergent power terminal in series and selectively supply power while a mobile rod moves along with a straight route, thereby drastically reducing an installation space. CONSTITUTION: A power switch(100) comprises a mobile rod and a driving power transfer bar(160). The mobile rod reciprocates while at least one area of the mobile rod contacts a load terminal(117). One end of the driving power transfer bar is coupled with the mobile rod and the other end of the driving power transfer bar is coupled with a driving unit(140) so that the mobile rod transfers driving power to the mobile rod to reciprocate between a commercial power terminal(123) and an emergent power terminal(133).
