Switching device housing has elastically deformable structure with adjacent elements along longitudinal axis of housing with curved transverse walls aligned in same direction

摘要

The housing is adapted to be fitted in the concrete between two walls and contains two housings (2,3) and an elastically deformable structure (10) that joins them. The structure has at least two elements (11) adjacent to each other along a longitudinal axis of the housing with curved transverse walls (12) aligned in the same direction.
