ABSTRACT:
A group wiring device which has built-in light emitting means and switch mechanism coupled with wire pair receptacle thereof. The switch mechanism is normally on a “CLOSE” status but can be switched to an “OPEN” status when a plug mates with the wire pair receptacle. When the switch mechanism is “CLOSE” and a testing voltage is applied to the circuit of the light emitting means, the light emitting means will emit light for assisting wire pair identification. After the process of wire pair identification is complete, the group wiring device is deemed to be in normal operation, that is, to perform ordinary signal transmitting functions. The wire pair receptacle will then be mated with plug of network cable so as to drive the switch mechanism to become “OPEN”. Therefore, the circuit of light emitting means becomes an open circuit and provides no function at all. As a result, the built-in light emitting means and switch mechanism of the present invention will not result in “loop back shorting” nor disrupt the communication at all.
