Abstract

A pane arrangement directed to a heatable composite pane having a capacitive switching region, including a substrate and a cover pane is disclosed. At least one intermediate layer is arranged between the substrate and the cover pane. A carrier film having an electrically conductive layer is arranged between the substrate and the intermediate layer or between the cover pane and the first intermediate layer. The electrically conductive layer forms a capacitive switching region having a contact region, a supply line region, and a connection region. The supply line region electrically connects the contact region to the connection region that can be electrically connected to a sensor electronics system. A heating wire and at least two busbars are arranged between the substrate and the cover pane, wherein one end of the heating wire is electrically connected to one of the busbars. A capacitive sensor electronics system is electrically connected to the connection region via a first input and to the heating wire or to the busbars via a second input.
