1. An automotive laminate system comprising:
an outer glass layer;
an inner glass layer;
at least two plastic bonding layers;
at least one switchable film layer having a set of opposite facing electrode layers separated by a dielectric layer,
wherein at least one portion of at least one electrode layer is electrically isolated at direct current from the remaining portion of the electrode layer,
wherein said at least one isolated portion is provided with an electrical connection means; and
a controlling means electrically connected to said at least one isolated portion by means of the electrical connection means, wherein a user contact with said at least one isolated portion causes a change in capacitance detected by the controlling means which produce a control response;
wherein said at least one isolated portion is configured to switch light transmittance independent of the remainder of the film.
