Description

The WS4-216B ELKO Pure White (Jumitech J350607) is a wireless, battery-free push-button switch with four buttons and Casambi Bluetooth connectivity, built for wall mounting with no cabling. Same battery-free construction as the 2-button variant – powered by the energy from the button press itself (energy harvesting) and never needs a battery change or mains connection. Four buttons give more programmable functions than the 2-button version, such as separate control of four different luminaire groups, four scenes, or a mix of on/off and dimming functions depending on how the switch is configured in the Casambi app. It mounts wirelessly on a wall and communicates directly with the Casambi Bluetooth mesh with no intermediate box or wiring. The ELKO Pure White design matches the Nordic ELKO range's white, minimalist look. No electrical rating (voltage/current) applies, since the switch only sends wireless signals and doesn't carry a load directly. Suited to rooms or spaces that need more functions from a single switch point – a living room with several lighting scenes, for example – with no new cabling or battery maintenance.
