Extension JO and to maintain alignment between these! Parts

The structure allows the contact to be removed in each longitudinal direction. A tool 80 can be used for insertion into the recess and this can be used from either end as far as the formation of the contact is concerned. It however, it happens more often that the contact is set or arranged so that it is because of the space problem or for other reasons can actually only be used from one side, namely for practical reasons from the so-called "front end" or the right end according to fig. 4 to 6. Im broad sense and without spatial limitations of the ones mentioned In one example, the tool can be inserted into the hat 46 (FIG. 9) until it is inclined Contact surface 76 of notch 68 whereupon the tool pulls the notch inward over shoulder 32 bends out. The contact is pulled out to the left. Likewise, the tool can be different from the opposite End can be inserted into the groove 44 (Fig. 10) until it touches the stop 66, which is inwardly is bent beyond the shoulder 34, whereby the Pulling out the contact is made possible. When the contact is brought into a position where it is not is possible to insert the tool from either end, the most common pail occurs that it is only in the indicated Direction can be used, i.e. as it is shown in the Pig 4 to 6 It is, however, desirable that the contact can be removed in either direction and the invention enables it to be carried out
