Abstract

The essential element of the device is a toothed switch wheel (8), arranged between date ring toothing (3) and day-of-week ring toothing (4). Two switch tongues (12, 13) are punched out from the said switch wheel and bent out from a plane of the latter. These tongues run essentially radially and protrude with their ends to different height levels. The tongue (12) with the higher-lying end forms an acute angle with the plane of the switch wheel. The aims in particular are to make production more simple and to make the switch wheel less expensive. <IMAGE>
