A touch-controlled assembly adapted to an electronic device is provided. The electronic device has a front casing, a rear casing and a display surface, where the display surface is located on the front casing. The touch-controlled assembly includes a circuit board and at least one touch key. The circuit board is disposed between the front casing and the rear casing. The circuit board has at least one pad, which contacts one surface of the rear casing. The at least one touch key is disposed on another surface of the rear casing for corresponding to the at least one pad, where an orthogonal projection of the at least one touch key on the at least on pad is partially overlapped with the at least one pad.
