Abstract: A switchable laminated glazing with improved bus bar that solves the problem of inhomogeneities and reduce the cost of its fabrication by providing a laminated glazing that comprise a switchable layer (14) that has an active material sandwiched between two conductive coated plastic layers (8), at least two bus bars (20) in electrical contact with the respective conductive coated plastic layer (8), and at least two pliable conductive media (12), each of them between the respective coated plastic layer (8) and bus bar (20). The area covered by pliable conductive medias (12) is substantially less than the area covered by bus bars (20). The invention provides an improved lower cost bus bar by sparing use of a pliable conductive media and by using a pliable conductive media in different kind of configurations.
