Dim a light
One dimmed circuit on channel 1, with a second channel spare
The dimmer sits on a DIN rail in the switchboard. Mains comes in on L and N, and O1 carries the dimmed active out to the light. A push button on SW1 switches the light with a press and dims it while held. O2, with its buttons on SW3 and SW4, can dim a second light the same way. Dimmable lights only, up to 200 W a channel.
