A switch arrangement for the selection of joining elements, which comprises a switch that comprises at least three supply points in which joining elements can be supplied to the switch in a position-oriented manner. Furthermore, an output point is provided where joining elements can be output in a position-oriented manner, the switch comprising a conveying element which has at least three receiving compartments each being adapted to receive a supplied joining element each at the supply point. A conveying element can convey the joining elements from a receiving position to an output position from the supply point to an output point, which is fixed relative to the supply points, and output.

Switch arrangement for the selection of joining elements

The invention relates to a connecting element () for producing a component connection () of two components () lying against each other by means of the connecting element (), which is welded to the lower layer ()&#x2014;the base layer&#x2014;by friction, wherein the connecting element () has a shaft (), which has a shaft segment () and a head () having a flat surface () lying on the top side of the head for transmitting the axial force, wherein a drive cutout () is introduced into the flat surface () in order to transmit a torque. The invention is characterized in that a continuous diameter increase starting at an ascent level (A) on the shaft segment () to the bottom side of the head results, wherein the distance from the ascent level (A) to a head bottom-side level (K), which has the greatest distance from the shaft end, is less than half the difference between the head outside diameter and the shaft diameter at the ascent level (DA&#x2212;DS)/2 (D) and greater than a quarter of the difference between the head outside diameter and the shaft diameter at the ascent level (DA&#x2212;DS)/4 (D).

Connecting element for producing a friction-welding connection

The invention relates to a rotary hopper feeder () for conveying and separating elements () which have at least one shaft, comprising a rotary feeder () with radially oriented conveyor cells () for conveying the elements (), said rotary feeder () being at least partially surrounded by a hopper wall (). The invention is characterized in that said conveyor cells () have holes () at the cell edges () and below the rotary feeders (), near the holes (), a rolling surface () is provided on which at least parts of the shafts of the elements () with shafts are supported and made to roll as they are conveyed.
