ABB KALO BELL SWITCH is a push switch which is a momentary or non-latching switch which causes a temporary change in the state of an electrical circuit only while the switch is physically actuated. The elegance of the Kalo design series lies in its simplicity and purity. The neutral white design perfectly complements any interior. Now you can fully devote yourself to interior design and fitting – because the Kalo design line is affordable and at the same time branded.
