To avoid lifting-off between the roller and the cam, a second contact is used between a second roller 2 connected to the first roller or merging therewith and a second cam 10 connected to the first cam or merged therewith, the directions of application of the two roller-cam contacts being opposite. The invention applies to controlling access to urban rail networks.
