| 摘要 |
The present invention relates to an electric installation device, such as an automatic switch, that comprises a housing made of a plastic material. The housing contains a number of constituent members which are mounted, so as to be capable of movement, on steel rods attached in said housing and used as pivots. According to the present embodiment, two of said pivots are constantly interconnected by a force connection using a crossbar located outside the housing so as to define preferably an integral U-shape bridge, whereby outside forces are directly transferred from one pivot to the other without being applied to the housing. |
