The present application provides a switch element and a switch system, pertaining to the technical field of switches, for resolving the problem of the large overall structural dimensions of switch elements in the prior art. The switch element comprises: a bottom case and a panel that are mutually engaged, and a strong current board, an isolation plate, a weak current board, a gasket, an on/off key, and a cover plate sequentially arranged between the bottom case and the panel, and the on/off key passing through the cover plate and extending out of the panel. A strong current region and a weak current region are provided on the strong current board, and a first separator is provided at one side of the isolation plate facing the strong current board, and when the isolation plate is in contact with the strong current board, the first separator separates the strong current region from the weak current region. The switch element uses the isolation plate to isolate the strong current board from the weak current boar
