With this practical 2 gang dimmer switch, you can easily dim two light sources from 0 - 100%. The dimmer works in combination with our dimmable LED bulbs, however you can also dim your own light sources with it. You can set the maximum percentage to which the bulbs can be dimmed with the adjusting screw. The dimmer has an electronic fuse and is protected against overloading, short circuits and incorrect connection. In case of a malfunction, the dimmer will reset itself without any damage. The two buttons on the dimmer allow you to switch between dimming modes Phase cut-off/on.
