Visual call installation insert

摘要

The invention relates to a visual call installation insert to be mounted in flush-mounted boxes. The usual support frame for the conductor board (printed board) is obviated by directly screwing the conductor board onto the flush-mounted box, the conductor side facing the covering plate. The space for components in the flush-mounted box is thus increased, SMD (surface-mounted device) components can be operated from the cover plate and membrane keyboards (sealed keypads) can act directly on the conductor side, facing the cover plate, of the conductor board.
