SO08A01KNX ships as bare hardware; the key set, a PO71 cover frame and an FO71A01 metal frame are ordered separately to suit the interior. This layout gives four half-buttons in the left column and two tall buttons in the right column, each key backed by its own RGB LED and freely programmable in ETS.\u003c\/p\u003e\u003cp\u003eThe finish is metal, black (MV-BK), one of the four 2026 additions to the OL-U Metal Edition beside the original silver (MT-SH); the MV code supersedes the earlier MT code for the coloured metals. The same tone runs across the BKxxMV-BK key sets and every PO-series frame format, so keypad, thermostat and adjacent receptacles can share one metal. Other tones: champagne (MV-CH), gold (MV-GO), bronze (MV-BR).\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eLayout: 4 left half-buttons and 2 right full-height buttons\u003c\/li\u003e\n\u003cli\u003eFinish: metal, black (MV-BK) — OL-U Metal Edition\u003c\/li\u003e\n\u003cli\u003eSnap-on fit over the device, under the cover frame; individual keys lift out with a flat screwdriver\u003c\/li\u003e\n\u003cli\u003eEach key position backed by a device LED (RGB on SO08A01KNX) and freely assignable in ETS\u003c\/li\u003e\n\u003cli\u003eInterchangeable with the other OL-U key sets (MT, MV, FX, PL) — re-dress installed hardware without rewiring\u003c\/li\u003e\n\u003cli\u003eWorks with PO71A01 (2-module), PO71A03 (3-module) and the 71+xx double frames\u003c\/li\u003e\n\u003cli\u003eClean with a soft microfibre cloth and water or neutral soap only; no solvents or abrasives\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eKey set (button kit) for OL-U KNX wall devices\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKeys \/ layout\u003c\/td\u003e\n\u003ctd\u003e6 keys: 4 left + 2 right\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish \/ colour\u003c\/td\u003e\n\u003ctd\u003emetal, black (MV-BK)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003emetal, black finish\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible hardware\u003c\/td\u003e\n\u003ctd\u003eSO08A01KNX\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible cover frames\u003c\/td\u003e\n\u003ctd\u003ePO71A01xx, PO71A03xx, PO71A71 \/ A55 \/ A45 \/ A60 doubles\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDevice footprint\u003c\/td\u003e\n\u003ctd\u003e71 x 71 mm (2.80 x 2.80 in) OL-U front\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer part no.\u003c\/td\u003e\n\u003ctd\u003eBK42MV-BK\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eRelated Products\u003c\/h3\u003e\u003cp\u003eFits SO08A01KNX.
