Item no.: 0070002

The ELPA 7 electronic staircase time switch ensures safe and reliable lighting with advanced features for modern installations. It prevents sudden darkness with a switch-off pre-warning, supports immediate secondary switching, and offers a toggle function for permanent light.

Built with zero-cross switching, it protects relays and handles high lamp loads with ease. Its automatic 3- or 4-conductor detection makes installation simple, while electronic overload protection ensures long-lasting performance.

Compact, accurate, and energy-efficient, the ELPA 7 is the ideal solution for stairwell lighting in residential and commercial buildings.
