The SONOFF ERBS is an auxiliary shutter control switch specifically designed for use with the MINI-RBS module. It is especially useful in installations where the wall mounting box depth is limited – featuring a compact, slim profile.

Made of durable polycarbonate plastic, it is fire-resistant, scratch-resistant, and resistant to deformation over time. The clip-on design allows for quick and easy installation, while the ergonomic, micro-curved button ensures a more natural and comfortable user experience.

With an ultra-thin body (only 21 mm thick), it fits perfectly into European standard round wall boxes (Φ60–80 mm) or 86-type wall boxes. Both user experience and aesthetics are outstanding.
