Dimmer double twist insert white porcelain

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

The double dimmer is bi-directional and has a so-called crown function, which means that it is used to dim two separate light sources.

The can dimmer, sold separately, is placed in appliance boxes in the wall. Combine the switch with optional frame and knob sold separately. See related products.
