A touch sensitive control panel is described. The control panel comprises a sensor surface in which a plurality of sensor areas are arranged and a circuit board offset from the sensor surface. The circuit board has an electrical contact associated with each of the sensor areas. The electrical contacts are connected to capacitance measurement circuitry. The control panel further comprises a guide block having a first side facing the sensor surface, a second side facing the circuit board and a plurality of channels extending from the first side to the second side. A plurality of resilient electrical conductors pass through the channels to connect between the sensor areas and the electrical contacts on the circuit board, such that the capacitance measurement circuitry is coupled to the sensor areas. The sensor surface may be curved with the resilient electrical conductors having lengths dependent on a separation between the electrical contact and the sensor area between which they connect so as to accommodate for the curvature of the sensor surface.
