The module housing has a pressure-tight wall (2) with an electrical module (3) with a contactless switch (4) that is protected against explosive atmospheres. The switch has a switching device (7), such as a permanent magnet, that is relatively movable from outside by an operating device, and sensor circuitry (8), e.g. with a Hall sensor. A dividing sub-surface (9) of the module housing wall is arranged between the switching device and the sensor circuitry. |
