RL 50: Difference between revisions

This brown element on the top right of picture 1 is a heating element, which pushes out a small plastic rod if a voltage is applied on the terminal on the top left of the element, and thereby opening the blinds. It seems that there is always a voltage applied to the element. The light bulb on the bottom right of the picture 1 is lit up and probably indicating that there is a voltage applied to the heating element.
