Cross coupler insert white porcelain

Classic recessed switch in white porcelain without knob and frame in a design that was common in Europe in the first half of the 20th century.

This switch has a so-called cross function, which means that it should only be used if more than two switches are to control the same light source from different locations in a room, staircase or corridor. The cross-function switch is then mounted between two staircase switches.

If an ordinary switch is required to turn a light source on and off, or if two switches are connected to the same light source, a step switch should be selected instead.

Combine the switch with optional knob and frame sold separately. See related products below.
