Abstract
An electrically dimmable window ('EDW') system comprising an EDW, a control switch, and a controller. The switch and controller control the light transmittance level of the EDW. State indicators indicate when the EDW is in transition from one light transmittance level to another level. When there is no transition in light transmittance level, the indicators may denote the current light transmittance level of the EDW.
