■ Staircase time switch, electro-mechcanical
■ 4 conductor with floor lighting connection
■ 3 conductor without floor lighting (no longer permitted for new systems)
■ Retriggerable
■ 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
■ Screw terminals
