Twilight Switch TS-42-2 – Dual Threshold Light Control 230V
The TS-42-2 twilight switch automatically turns ON and OFF loads such as street lighting, building lights, and illuminated signs at dusk and dawn.
Its dual independent thresholds provide precise, energy-efficient, and environmentally friendly control, eliminating the hysteresis common in standard twilight switches.
