A special highlight: the OKTO 540 BN switches all light sources completely silently. This makes it perfect for hotels, bedrooms, patient rooms, theaters, or high-end residential projects where every clicking noise is disruptive. 

Thanks to its fully encapsulated electronics, the push-button switch is suitable for damp locations, maintenance-free, and durable. The pre-assembled connection cables enable quick, safe, and error-free installation – a clear advantage for electricians in their everyday work. 

The electronic and electromechanical OKTO latching relay for series installation enable simple and convenient lighting control of a consumer via any number of push buttons. This makes them ideal for lighting control in hallways and corridors of apartment buildings, functional and commercial buildings, common rooms, and private living areas.
