The retractive mechanism returns the rocker to its original position once released, providing a momentary press-to-make action rather than a latching switch. This makes it suitable for door entry systems, bell pushes, stairwell lighting timers and dimming control when paired with compatible dimmer modules.\u003c\/p\u003e\n\u003cp\u003eDesigned for architrave mounting where standard switch widths will not fit, the switch measures 86mm high by 32mm wide with a 9mm plate thickness. It requires a minimum 16mm back box depth, making it compatible with shallow pattress boxes used in door frames, narrow wall sections and partition walls. The SP (single-pole) 2-way configuration allows it to be wired as part of a two-way lighting circuit or as a standalone momentary switch depending on application.\u003c\/p\u003e\n\u003cp\u003eThe white thermoset resin construction provides mechanical strength and heat resistance across commercial and residential installations. The 10AX rating handles switching loads up to 2,300W on 230V 50Hz circuits, suitable for controlling multiple lamps or interfacing with relay packs. The IP20 rating limits use to dry indoor locations away from moisture ingress. The anti-microbial properties in the resin reduce surface bacteria growth, making the switch suitable for healthcare, hospitality and food preparation environments where hygiene standards apply.\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\u003e86mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e32mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth\u003c\/td\u003e\n\u003ctd\u003e22.9mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e13.1°\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecessed Depth\u003c\/td\u003e\n\u003ctd\u003e9.9mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMin.
