Part of electro- or electronic housing, particularly housing base, for fixing on structure, has element related to direction of gravitational field of earth, where aligning element is set to incorporate unit for determination of levels

摘要

The part (2) has an element (5) related to the direction of the gravitational field of the earth. The aligning element is set to incorporate a unit for determination of levels, where the function of the aligning element is to incorporate a level, particularly a scale in a stable equilibrium. The aligning element is comprised of a surface (8,9) that is designed for receiving a level, particularly a water level. The aligning element is also comprised of a single continuous surface for receiving the level, where the surfaces are formed on the body (6,7) of the aligning element.
