A composite actuating device is provided for use on an electronic device, such as an electronic notepad or an electronic dictionary machine. The composite actuating device of the invention includes a casing, a cover adapted to be reclosably hinged to the casing and having a locking structure provided in one end thereof, and a power switch mounted in the casing, a button which can trigger the power switch when operated; and a latching device which is capable of locking the cover in closed position on the casing when engaged with the locking structure on the cover, the latching device being linked to the button such that the latching device is disengaged from the locking structure on the cover when the button is operated to trigger the power switch. This allows the actions of unlocking the cover and switching on the power of the electronic device to be simultaneously achieved simply by operating one button by the user.
