Abstract

The invention relates to an installation switching device comprising a housing, with a front and rear face, a mounting side, front and rear narrow sides and wide sides, and with two screwless terminal connections with in each case at least one clamping spring for the connection of connecting conductors which are fixed in position in a terminal connection space of the housing. The terminal connection space is open towards the housing wide sides and towards the face. Each terminal connection is covered by an associated terminal cover part connected pivotably to the housing, which has a terminal face with a number of terminal openings corresponding to the number of connecting conductors to be connected, and guide means moulded onto each terminal opening for the connecting conductors, which also has two side areas which cover the terminal connection laterally in the direction of the wide sides. Spring actuating means are moulded onto the cover part and are constructed in such a manner that, when the cover part is swivelled against the clamping spring they load the latter so as to open it.
