A cross-type limit switch () with a housing () that contains a gear mechanism () that includes a cover plate (), base plate (), and intermediate plate (). The intermediate plate () has first and second cutouts () within which respective gearwheels () are arranged. The first and second gear wheels () have respective plugthrough openings (), and a shaft () coupled to an actuating lever () outside the housing is rotatably mounted in a first bearing arrangement () connected to the housing. The actuating lever shaft () extends through the first plugthrough opening () of the first gear wheel () for rotating and radially locating the first gear wheel (). A rotary switch () arranged in the housing () has a switch shaft () rotatably mounted in a second bearing arrangement () that extend through the second plugthrough opening () of the second gearwheel for rotating and radially locating the second gearwheel ().

A chain sprocket for link chains, for example, round link chains or profiled steel chains, has chain pockets for horizontal chain links. Chain pockets for vertical chain links are also provided. The chain pockets for the vertical chain links are separated from one another by teeth. The tooth flank surface of the tooth that a vertical chain link contacts under the effect of a load is dimensioned and profiled in a special manner. The dimensioning is such that up to a defined chain load the vertical chain link does not contact the tooth flank with its nose. A contact between the tooth flank surface and the nose of the respective chain link occurs only above a defined chain load.
