An actuating module includes an actuating member, a magnetic plunger engaging the actuating member due to magnetic power and capable of disengaging the actuating member upon receipt of an actuating signal, and a flexible flat cable. The flexible flat cable includes a plurality of laterally connected data wires. The data wires includes at least one branch wire connected electrically to the magnetic plunger for transmitting the actuating signal to the magnetic plunger so as to release the actuating member.
