Abstract

An electronic housing system is provided which includes at least two, especially plate shaped, electronic housings which can be snapped onto a mounting rail. The housing system includes a locking system including at least two housing portions, namely a starter unit and an end unit, and a key element. The starter unit is constructed as a key receptacle and the end unit is constructed as a lock complementary to the key element. The two housing portions can be locked with one another by rotation of the key element in the end unit. The locking system further includes an intermediate housing portion for positioning between the starter unit and the end unit, whereby the intermediate portion has an intermediate end unit for interlocking with the end of the key element, and an intermediate starter unit.
