Toothing determined. The shell 12 is axially fixed to the fastening nut 4 by the interaction of perforations 19 in the jacket with an annular shoulder 20 in the nut.

Mode of operation: When the push button 10 is pressed in sufficiently far, the relaxation of the spring 13 pushes the locking slide 11 back along a diagonal D of the square (Fig. 5) so that it covers two sides of the push button 10 (which prevents it from tipping) , the release tab 11Λ exiting radially.

One is sufficient so that the elastic relaxation of the spring 7 can release the push button 10 again Pressure on the release tab 11 ^ 4.

The attachment of the push button and its locking system to the base plate 8 can of course can also be done in ways other than screws. So is z. B. in Fig. 7 the attachment by means of a Bayonet lock shown, with radial tabs 21 on the jacket 12 on a fastening part 28 are arranged, which is connected to the jacket 12 by pressing, flanging or in some other way is firmly connected, hook into L-shaped incisions in a socket 23.

In order to prevent involuntary detachment of the jacket attached to the socket 23, the Lugs 21 tightened axially at the edges of the incisions 22. For this purpose, e.g. screws 24 in Screwed nuts 25, which sit on radial extensions 26 of the socket, the screws on the Support the back of the base plate 8, advantageously an annular, preferably an elastic one Existing material spacer 27 axially between the tabs and the front of the Base plate 8 arranged around the socket 23

This attachment by means of a bayonet lock is advantageous because it is a particularly simple one quick insertion of the push button and a locking system, an economical structure thin punched cut-out parts, where no thread needs to be cut, besides that of the small nuts 25, any choice of the position of the housing and thus the release tab 11.4, the number of possible positions being the same as the incisions 22, and reliable compliance the selected position.

The shape of the push button can be modified further. So z. B. the cross section of the push button be triangular, then two of the three sides of the triangular face of the push button of the Locking slide are covered.
