Abstract： |
This invention relates to a single-pole double throw net switch for setting the switch between inner net and data-exchange host and the switch between outer net and the said host in a same circuit card, belonging to internet data-safe transferring technology fields. The invention comprises an RS232 signal-control receiving unit linked with the RS232 serial port of the data-exchange host to receive control signal, a controlling unit 1 to receive control signal from the said RS232 control-signal receiving unit, two same analog switches each of which is with a control-signal input ends linked with output ends of the said controlling unit, two chips with two signal-outputs, one of the outputs of each of which is linked with data-exchange host net interface. The invention is safe, flexible and has high property to price, and little signal distortion on net. |
