Central plate featuring 1 key with a ventilation icon symbol. This key is used for the control of mechanically controlled ventilation. Finishing colour: light grey.
Finishing set for two-way switch for mechanical motor control, light grey. The key and the intermediate plate (board) form one unit. The key on the central plate is indelibly imprinted with the ventilation symbol.
This central plate is surrounded with a flat edge that is equipped at all 4 corners with a rectangular opening, each containing a multi-positional snap hook. The construction of the central plate ensures that the flush-surround plate can always be attached flat to the wall, even in cases of untidy plasterwork. This works in two directions: If the flush-mounting box sticks out of the plasterwork, the multi-positional snap hooks can compensate for a 1 to 1.2 mm margin; if the flush-mounting box is sunk too deeply in the plasterwork, the snap hooks can compensate for up to a 1.8 mm margin. The flat edge around the central plate also has 4 round openings that ensure the correct positioning of the flush surround plate in relation to the central plate. After mounting all components (flush surround plate, finishing set and switch), no metal parts are visible thanks to the flat edge of the central plate. For dismounting the central plate, the flat edge is equipped with two notches indicated by a screwdriver symbol. The central plate can easily be dismounted using a slotted screwdriver.
