摘要

The system has a control and/or display element (14) on a mounting plate (12) for each device with a peripheral sealing element (18) between the plate and control/display element. The sealing element edge (20) in contact with the mounting surface is a peripheral lip with an outer edge region protruding towards the second edge (28), which has an essentially seamless transition into the control/display element to form a smooth closed surface.
