Sumum – excellence in simplicity

A Belgian brand, originated in a switch, designed simply. It became a product as pure as can be. The collection, brass switches, sockets and hybrids, quickly grew towards architectural hardware. Hardware combinations & matching finish on each item (faucets, doorhandles, cabinet handles....). And the design work continues with access control, lighting and interior objects.

We blend functionality with design, excellence with simplicity. We focus on perfection beyond details. We craft architectural hardware, smart and simple, nimble but elegant, compatible and pure. We are passionate about beautifully detailed, products.

Our products are the finishing touch of your home. They perfectly do what they were made for. And they subtly reveal who you are.

Qbus makes homes smart.

We turn the lights on when someone is present, we control the temperature room by room, we talk to the digital meter and decide where to consume energy, we allow elderly to live home longer sending alarms when something is wrong, and so much more.
