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. An axial end of the triggering portion is spaced at an axial distance b from an axially lower surface of the support portion, and an axial upper surface of the support portion is spaced at a distance h from the axially lower surface of the support portion, and b<h. The pressing portion is axially opened with a bowl-shaped groove extending to the triggering portion. The rubber dome provided by the present disclosure avoids the over-sensitivity phenomenon conventionally caused by lowering the triggering force of the thin film circuit switch by adjusting the conduction distance to make the triggering portion closer to the thin film circuit switch.

Thus, the conduction efficiency, i.e., the conduction agility at the time of pressing is improved, and the conduction performance for corner pressing is also improved, so that the key reaction is more agile.
