Keystone switch compatible with all keystone adapters for the civil series currently on the market, its peculiarity is that thanks to a new digital technique it is able to regulate the brightness of dimmable LED lamps with phase cut in Trailing edge with 230V mains voltage power supply without having to power it with the Neutral.

This makes the switch much more versatile in applications or replacements for old resistive dimmers with two-wire connection.

The brightness is adjusted by rotating the knob on the front from minimum to maximum and vice versa. By pressing "PUSH PUSH" the knob turns the light on and off, keeping the chosen brightness in memory even in the event of a power failure and return of the 230V mains voltage.

Less light means less electricity consumption, thus allowing for significant energy savings, while its small size allows for the keystone adapters to be attached and detached directly from the front without having to remove the frames from the wall electrical boxes.
