Description

- 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
