Stair switch black porcelain black knob

Classic surface-mounted switch in black porcelain with black porcelain knob in a design that was common in Europe during the first half of the 20th century.

This switch has a so-called staircase function, which means that it can be used as a regular switch to turn a light source on and off. It can also be used in rooms, corridors or staircases to turn on a light source at one end of the room and off at the other end. If staircase switching is required, two switches with staircase function are needed. If a light source is also to be controlled from a third switch, this must have a cross function.

In the side of the base there is an opening for cable exit for surface-mounted electrical wiring, but it can also be mounted for recessed wall box in combination with any of Fontini’s base plates.

For surface mounting on wood paneling or other flammable material, an insulating plastic base plate can be used as additional fire protection.
