Sun blind control

Sun blind control
Sun blinds, whether of the traditional awning kind or of the modern metal roller type, provide welcome shade in the summer and , in the case of the latter, also good protection against break-ins. Many of these blinds are operated by an electric motor. The control described closes the blinds when it gets dark outside and opens them again when daylight returns. This automatie operation can be overridden bya manually operated switch, so that the blinds can be opened or closed at any time of the day as required.
