Abstract

A capacitive switch is comprises a sensor area and with a reference surface in which the sensor surface and the reference surface are configured to produce an electric field (E) between them. The sensor surface and the reference surface are arranged substantially in a common plane such that an electrical field (E) is formed between them with an arched line of force. A coupling surface is configured to move in a plurality of directions in space with respect to the sensor surface and reference surface. A lighting element is configured to illuminate the capacitive switch when activated. A tactile feedback device provides feedback as the capacitive switch is being actuated.
