Earphone plug with switch device
An earphone plug applicable to different system specifications includes a terminal and a switch device. The earphone plug is inserted into an earphone jack of an external electronic device for transmitting signals by a plurality of exposed signal interfaces of the terminal. The switch device combined with the terminal has a first conductor and a second conductor. When the switch device is switched between a first mode and a second mode, the first conductor and the second conductor alternately contact with two of the signal interfaces. Thus, the signal transmission defined by the signal interfaces is changed and the earphone plug is applicable to electronic devices with different system specifications.
