Top-hat rail housing for receiving circuit board for process automation system, has contact which abuts top-hat rail at multiple points when housing is placed on rail

摘要

The housing has a flat metal member (4) for dissipating high frequency interference signals, conductively connected to at least one circuit board (2). The housing has a contact part (5) which extends through the back wall (3) of the housing, and automatically abuts the metallic top-hat rail at multiple points when the housing is placed on the top-hat rail.
