A fast disassembling joint structure includes a base part and a removable part. Such is utilizable to make thin film transistors and other circuitry. This results in a network with all digital baseband signaling and simplifies the network architecture so as to be all Internet Protocol andor all Ethernet compatible. The plug is removable from the drain port for allowing fluid to drain from the manifold. The switch member is connected to the light signal transmitter and commands the light signal transmitter to transmit the light signal.
