Abstract: This application relates to a signal transfer apparatus. In the apparatus, one of a plurality of switches is connected in series between a first end of each of first terminals in a first terminal group and a first end of each of second terminals in a second terminal group; a control module determines, from the plurality of switches based on apparatus connection setting, a plurality of target switches that need to be turned on, and sends a control signal for turning on the plurality of target switches to a drive circuit; and the drive circuit is connected to both the plurality of switches and the control module, and drives, based on the received control signal, the plurality of target switches to be turned on, so that signal paths between the first terminals and the second terminals that are connected to the target switches are connected.
