• Staircase time switch, electro-mechcanical
  • 3 conductor connection and floor lighting, but without secondary switching (no longer permitted for new systems)
  • Terminal layout same as ELPA 8
  • No closed-circuit current consumption
  • Toggle switch for permanent light ON
  • Reliable due to synchronous motor drive
  • Simplest possible time setting and direct delay time readout on absolute scale
  • Precision mechanics and therefore exact switching period
  • Very low sensitivity to interference
