The PIERRE Wave - Rounded Series 1 Gang 2 Way Secondary Light Switch (no Neutral) is the second position in a two-way arrangement. It does not switch the circuit itself — it sends the command to a Rounded Series 1 Gang 2 Way Main Light Switch, which does.

No strapper cable is needed between the two positions. Only a local supply is required at the Secondary, which makes two-way control practical to retrofit where no switch wire runs between the two points.

It operates without a neutral and will accept one where present, running from 100-240 V AC 50/60 Hz at 0.3 W standby, and communicates over PIERRE Wave (Zigbee 3.0, 2.4 GHz).

The front is tempered glass in grey, mounting to a 80x80 mm box. Always order it together with the matching Main switch — on its own it will not control a circuit.
