It has two jobs: it holds the switch firmly in place, and it gives the opening a clean, chrome-plated edge instead of a raw hole in the sheet metal. The part number is A529904989.\u003c\/p\u003e\n\u003cp\u003eIt usually gets lost during a repair – it is small, it rolls, and it never turns up again. But it is also replaced when the chrome plating has become stained, when the thread was stripped by overtightening last time, or when the switch can no longer be tightened and wobbles in the panel. A wobbling switch is not just a cosmetic flaw: every time it is pressed, it puts strain on the connections behind it.\u003c\/p\u003e\n\u003ch3\u003eWhen it's due\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eThe main switch wobbles in the panel or can be pushed in.\u003c\/li\u003e\n\u003cli\u003eThe decorative nut was lost during servicing.\u003c\/li\u003e\n\u003cli\u003eThe chrome plating is stained, tarnished or chipped.\u003c\/li\u003e\n\u003cli\u003eThe thread no longer grips properly or has been stripped by overtightening.\u003c\/li\u003e\n\u003cli\u003eThe front panel is being replaced and the trim parts are to be replaced with it.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eAt a glance\u003c\/h3\u003e\n\u003ctable class=\"ccc-compare-table\"\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eDecorative nut, purely mechanical\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInstallation location\u003c\/th\u003e\n\u003ctd\u003eOn the outside of the housing panel, at the main switch opening\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFits\u003c\/th\u003e\n\u003ctd\u003eRocket espresso machines – the documentation does not name a specific series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eScope of delivery\u003c\/th\u003e\n\u003ctd\u003eOne decorative nut.
