Ajax Oyster 46020.144.DY Wireless Wall Switch Double Button Light Control

The Ajax Oyster 46020.144.DY is a wireless, battery-powered double-button switch for triggering automation scenarios within an Ajax system — no new cabling required.

Where it fits on a job

For installers adding automation to an existing Ajax hub deployment, the Oyster gives end users a physical control point without running switch cable back to a relay. That makes it a practical retrofit for:

• Offices and retail units — a manual override next to a till point or entrance for lighting or connected devices, without disturbing existing wiring.
• Residential blocks — communal or in-flat light control as part of a wider Ajax automation setup.
• Warehouses — a wall-mounted trigger for automation relays covering signage, lighting zones or other switched loads.

How it works

Each button is assigned a separate command through the Ajax app, so one unit covers two independent actions — for example, one button for lighting and one for a connected relay. Communication runs over the Ajax Jeweller wireless protocol back to the hub, which is the same protocol used across the Ajax device range, so it sits alongside other Jeweller-connected sensors and modules on the same hub without extra receivers.

Installation notes

• Indoor wall mounting only
• Touch-sensitive button surface, slim square housing
• Battery powered — no mains or data cable needed at the switch position
• Requires a compatible Ajax hub and automation module already on site
