Recessed rebounding double dimmer in black 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.

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

Please note! Frame, knob and dimmer are purchased separately.
