A control box includes a shell, a display hole, an active member, an indicating member and an interlinking member. The display hole is formed in the shell. The active member has a turn-on end and a turn-off end and is pivotally connected with the shell so as to seesaw. The indicating member is movably disposed in the shell and has a first identifiable portion and a second identifiable portion. The interlinking member is connected between the active member and the indicating member to drive the indicating member to move. Accordingly, when the active member seesaws under the effect of an external force, the indicating member is driven by the interlinking member to show the first identifiable portion or the second identifiable portion in the display hole.
