The invention concerns a mechanical end-position stop device for sequence switches of the type which consist of a load coupler 10, a stepping selector 11 and an operating device 12. The stepping selector is operated from the operating device via a drive shaft 20 which is connected to a gear unit 21, 22 arranged in connection with the selector, which gear unit has a gearing ratio of the order of 10:1, which in turn drives a star gear mechanism 24, 25, 26. The stop device 34, 36 is arranged in direct association with the drive shaft 20 and is activated via a link arm 32 from the star gear mechanism if the stepping selector, due to a faulty connection of the operating device should attempt to go past any of its normal end positions. <IMAGE> |
