The module clips into the front of Knightsbridge Grid mounting frames (sold separately), forming part of a modular switch and socket system where individual modules are combined to create custom configurations.\u003c\/p\u003e\n\u003cp\u003eDesigned for residential, commercial and light industrial installation, the centre-off position provides an off state between the two switched circuits, preventing both from being live simultaneously. This configuration suits applications where dual circuit control is needed without overlap, such as switching between two lighting zones or controlling separate appliance circuits from one control point. The 20AX rating handles loads up to 4,600W on 230V mains.\u003c\/p\u003e\n\u003cp\u003eThe module body is constructed from white UREA polymer with an ABS mounting plate and steel terminals. At 24.8mm wide, the module occupies one standard Grid space and can be combined with other Grid modules (switches, sockets, dimmers, data outlets) in frames ranging from 1-gang to 6-gang width. The minimum 35mm back box depth requirement is standard for Grid installations and the IP20 rating suits dry indoor locations.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e56.3 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e24.8 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e7 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecessed Depth\u003c\/td\u003e\n\u003ctd\u003e18.7 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMin.
