Time relay for the КВ1.1 stairwell switch

A new variant of the stairwell switch, the КВ1.1, is now on sale.
The time relay for the КВ1.1 stairwell switch is an unenclosed version of the КВ1, КВ2 and КВ3 switches.
Thanks to its small size (36 × 19 × 13), this unit fits inside practically any standard switch plate housing.

Like the rest of the КВ family, the КВ1.1 switches lighting on and then off automatically after a preset interval.

The relay is used to control the lighting of floor corridors, stair landings, areas in front of refuse chutes and passageways, and replaces mechanical stairwell circuit breakers of types АВ-01-2,5/220 and АВ-2М.
