Theben Elpa 8

Staircase light timer, electromechanical. 4-wire with connection for floor lighting. 3-wire connection without floor lighting (no longer permitted for new installations). Can be switched on and off. No quiescent current consumption. Toggle switch for continuous light. Maximum reliability thanks to synchronous motor drive. Simple time setting and direct reading of the delay time on an absolute scale. Precision mechanics and therefore exact switching time. Very high resistance to interference.
