This application provides a switch assembly, a button module, a combined button, and an electronic device. Abutting parts that are of a terminal pair and that are in contact with a dome and contacts that are of the terminal pair and that are electrically connected to an external circuit are accommodated in an accommodating member of the switch assembly, and the two contacts of the terminal pair are disposed adjacently. An external circuit board may be electrically connected to the two contacts of the terminal pair, to be electrically connected to the switch assembly. The external circuit board does not need to be disposed at a bottom of the switch assembly, or does not need to be stacked on the switch assembly. No glue filling space needs to be reserved on a back surface of the switch assembly. This helps reduce a width of the switch assembly.

The present disclosure discloses a rubber dome with advanced conduction which includes a support portion, an elastic connection portion, and a pressing portion connected in sequence, the pressing portion having a columnar triggering portion at an axially inner side thereof.
