Extension unit operation

Up to five rotary control elements for the control specific lamps can be installed with the Busch-Dimmer® units. This works perfectly due to the practical rotary dimmer extension unit - and naturally, of course, also with existing two-way and intermediate switching circuits. And the best is: The operation of dimmers and extension units is completely identical. Also the comfortable memory function remains the same for each extension unit.

Retrofitting comfort

 It is possible to retrofit two-rocker conventional light switch with a dimmer without any structural changes. There are two options. When pressing the dimmer knob on a switch-dimmer, an additional load (max. 6 A) can be switched, such as a second lamp, for example. With 2gang dimmers one can control a lamp with each rocker half. A brief press: on and off. A long press: dimming.
