Sven — [Please pardon my unbelievably tacky image edit!] Notice there is one important difference between the two. Your block (1) can be oriented so that operating the switch correctly isolates the movable switch blades and the fuseholders—more “traditional” from a safety standpoint.

In Tim’s shot, (2) the fuses are on the line side of the switch, or if the block was mounted reversed 180°, (3) gravity would be working against keeping the switch blades deenergized. In the reversed case, they would have the undesirable tendency to ‘fall’ closed.
