Product Description
What it does
The Ajax Oyster 46020.144.DY is a wireless, battery-powered double-button wall switch for triggering automation scenarios inside an Ajax security and smart automation system — no wiring back to a relay required.
On the wire
- Communicates over the Ajax Jeweller wireless protocol to a supported Ajax hub.
- Battery powered, indoor wall mounting only.
- Touch-sensitive dual-button interface — each button takes a separate command assigned through the Ajax app.
- Slim square form factor for wall installation alongside other switches.
Where it fits on a job
Two independent buttons mean one unit covers two automation triggers — lighting on/off, activating a relay, or firing a routine involving other connected devices. Because there's no cable run, it drops into retrofit jobs: adding a manual override point in an office, a residential unit already running Ajax automation, or a commercial space where a relay is controlling switched loads.
Compatibility
Designed for integration within the Ajax ecosystem — works with Ajax hubs and automation modules that support Jeweller-protocol devices. Confirm the specific hub and module list against your current Ajax system configuration before specifying.
This SKU is also listed under the reference Ajax-46020.144.OY.
