Abstract
An LED ring or light guide for a mechanical or mechatronic closure system that includes an actuating means, such as socket wrench receptacle or swivel handle, which is rotatably supported in a housing or tray. The LED ring or light guide also includes a retaining nut or bearing piece that can be screwed on with the housing or with the tray with the intermediary of a thin wall such as door panel of a sheet-metal cabinet or sheet-metal housing. A light ring surrounds a flange of the housing or of the tray, and a flexible foil is arranged between light ring and thin wall. The flexible foil carries light emitting diodes (LEDs) and relays the light thereof. A closure indicator integrated in the actuating means is achieved in this way.
