A device for spatially resolving a projected capacitive touch detection. The device includes an electrically insulating substrate with a first and a second type of electrically conductive surfaces, and a through-hole. The first type of electrically conductive surfaces are connected in rows to form transmitting electrodes. The second type of electrically conductive surfaces are connected in columns to form receiving electrodes. The first type of electrically conductive surfaces includes non-deformed first type of electrically conductive surfaces and deformed first type of electrically conductive surface(s). The second type of electrically conductive surfaces includes non-deformed second type of electrically conductive surfaces and deformed second type of electrically conductive surface(s). The first type of electrically conductive surfaces and the second type of electrically conductive surfaces are arranged in an alternating manner. The deformed first and/or second type of electrically conductive surface(s) abut the through-hole.
