In general, switches and socket outlets etc. can be exchanged very easily. If you have already installed frames from a Gira System 55 design line this is particularly simple – because all frames from the Gira Standard 55, E2, E3, Event, Esprit, and ClassiX ranges are interchangeable. Simply exchange the frames – the existing inserts can continue to be used. This is a simple way to give the room new highlights in terms of colour and material appearance.
