The stairwell light switch controls lighting in floor corridors, stair landings, the areas in front of refuse-chute hatches, passageways and similar spaces. It switches the lighting on and turns it off automatically after a set interval.
To ДБН В.2.5-23-2003, in new and refurbished residential buildings the artificial lighting of stairwells, floor corridors and the areas in front of refuse-chute hatches must be controlled by flush-mounted switches with a 1–5 min delay, rated up to 2 A, 220 V, 50 Hz.
Replaces АВ-01-2,5/220 and АВ-2М mechanical stairwell timers.
