Automatic telephone line switcher that enables a single fax, modem, answering machine or other device to be connected to TWO separate incoming phone lines at the same time. The circuit automatically detects which line is ringing and connects the fax (or other device) to that line.
This can save you having to have duplicate machines in a small office. The circuit always returns to its default line (#2) so that outgoing calls can be made.
Kit version includes solder for assembly.Specifications
