<p>The element (1) has end surfaces (12, 13) extended transverse to front and back surfaces (10, 11) and arranged opposite to each other. A passage channel (16) i.e. blind hole, is extended between the front and back surfaces, to hold an electric line (4). The electric line is connected to an elongated rod-like capacitive sensor (3) of an operating device that actuates an electrical device i.e. illumination device, in a contactless manner. Cross-sectional dimension of the sensor is smaller than cross-sectional dimension of the passage channels. The element is made of timber, plastic, stone or glass.</p> |
