Built-in Dimmer & Switch Homematic IP EQ3-ADA-J2 — White, 55×55×20 mm

Homematic IP EQ3-ADA-J2 is a built-in dimmer and switch in white finish designed for recessed installation and integration into modern electrical systems. The compact housing (55×55×20 mm) combines dimming and switching functions in a single module intended for lighting control in residential and commercial environments. The device supports retrofit smart home setups and centralized light control panels where space is limited and precise, flexible light regulation is required.

Advantages

The unit provides combined dimming and switching in a compact form factor suitable for flush mounting behind standard switch frames. Its white finish and small dimensions allow discreet integration into existing installations. Compatibility with the Adapter set Jung J2 enables simple integration with multiple switch series without extensive rewiring, allowing wireless Homematic and Homematic IP actuators to replace existing switches with minimal installation effort. The integrated functions allow both on/off control and stepless light adjustment where supported by connected loads.

Suitable for

• Adjustable indoor lighting in homes and apartments
• Retrofit smart home conversions using Homematic and Homematic IP actuators
• Centralized light control panels and switch clusters with limited space
• Integration behind existing switch series using the Jung J2 adapter set
• Commercial interior lighting where discreet, recessed control is required

How to use

Install the built-in dimmer and switch in a suitable installation box behind the desired switch location, following local electrical regulations and switching off power before installation.

Recommendations

Use the adapter set Jung J2 to integrate the module with supported switch series (A 500, A creation, A plus, AS 500, AS universal) for a low-effort retrofit. Verify compatibility of connected lamps and loads with dimming operation, and follow the manufacturer’s documentation for pairing, load limits and mounting depth to ensure safe and reliable operation.
