The PIERRE Wave - Rounded Series 3 Gang Light Switch (no Neutral) controls three independent lighting circuits from one plate, and from the PIERRE system.

It runs without a neutral conductor, which is what makes it a retrofit switch: in older properties the switch drop is usually a single live, and a switch that demands a neutral cannot be fitted without rewiring back to the ceiling rose. It will accept a neutral where one is present, which allows very small loads or no load at all on a channel.

Running from 100-240 V AC 50/60 Hz, it is rated 2 A, with each channel switching 5-500 W for incandescent, 5-150 W for compact fluorescent and 5-150 W for LED lighting. On a no-neutral circuit the LED minimum matters as much as the maximum — very low loads may need a bypass.

It communicates over PIERRE Wave (Zigbee 3.0, 2.4 GHz) and repeats for other PIERRE Wave devices. Standby consumption is 0.3 W.

The front is tempered glass in grey, mounting to a 80x80 mm box with 60 mm fixing centres.
