Abstract: A data transfer system is disclosed, which comprises a serial controller and a switch device. The switch device includes a first serial port, a second serial port, and a transferring unit. The first serial port and the second serial port are individually configured to transmit a first type signal to the transferring unit. The transferring unit selectively switches a transmission of the first type signal from either the first serial port or the second serial port to the serial controller. The first serial port and the second serial port are individually configured to transmit a second type signal to the serial controller, wherein the first type signal is faster than the second type signal in transmission rate.

Abstract: A reading apparatus suited for being inserted into a first electronic device or a second electronic device is disclosed. The first electronic device has a first interface receptacle. The second electronic device has a second interface receptacle. The reading apparatus has a first interface-module and a second interface-module. The first interface-module comprises a plurality of pins corresponding to the first interface receptacle and used to transmit a first interface signal. The pins comprise a plurality of first pins which are disposed on a top surface of a circuit board, and comprises a first positive-negative direction determining pin which is used to confirm whether the first interface-module is positively inserted or negatively inserted into and the first interface receptacle. The second interface-module comprises a plurality of conduction pad corresponding to the second interface receptacle and used to transmit a second interface signal.

Abstract: An electrical connector includes a connecting casing, a terminal assembly and a receiving member, in favor to attaching on a cable. Each rear end of a plurality of terminals of the terminal assembly protrude to a terminal carrier of the terminal assembly in furtherance to penetrate through the receiving member up till the terminals being exposed out of a rear-side socket of the connecting casing.
