Staircase switches
Staircase timer switches not only automatically delay the switching off of lights, but also allow for adjustable delay times, thus achieving energy-saving efficiency.
Staircase switches automatically switch lamps off after an adjustable period of time and are mainly used in stairways, basements, corridors, elevators and lobbies.
ALST8 staircase time switch is available in DIN rail. It runtime from 1 minute to 7 minutes, and fitted with electronic overload protection.
Toggle switch for permanent light ON
No closed-circuit current consumption
External push switch control
Reliable due to synchronous motor drive
Low sensitivity to interference
Precision mechanics and therefore exact switching period
