SNO Dusk switches

Characteristics of SNO Dusk switches

The SNO dusk switch reacts to changes of daylight intensity – the electrical circuit switches on when the daylight intensity decreases and switches off when it increases. The light intensity level can be individually pre-set by the regulating disk. The reaction time for exposure skip-change is 10 seconds minimum. The dusk switch can be successfully used for automatic control of night illumination in store windows, passages, streets, gardens, billboards, etc.

The SNO dusk switches are produced as the 960 20 model having a built-in sensor and the 960 21 model with an external sensor.
