The present invention is related to a switchboard comprising a PCB (10), a membrane (20) and at least one switch contact (11, 21) of the force-sensitive resistor type interposed between the PCB and the membrane and characterised in that on top of said at least one switch contact at least one mesh (31) of electrically conductive tracks is provided for protection against tampering. The conductive mesh is printed on the membrane, and is interposed between membrane and switch contact. The membrane is glued onto the PCB.
