A position change switch of this type has The cover plate 3 shown in FIG. 3 consists of a housing made of an insulating material, the inside of which is made of an electrically non-conductive material, in the shape of a hexagonal cell; Each side of that one surface, for example a star-shaped, electrically quiet cell, is provided with a conductive lamella which is applied in any manner on the central surface line, so that the conductive lamellae are applied in any manner. These electrically conductive strips are arranged on the housing revolving ball when the position is changed that, when combined with a section of the ring 1 and the cover plate 3 made of insulating material, they each again approximately cut across a conductive section to 45 the centers of the Vaults 2 cover,

Strength and the slope 12 of the octagonal "Pyramid" can be changed. D're number of side faces the pyramid can also vary.

Instead of a ball 4, a roller-shaped body with a cylindrical shape can also be used.

The cover plate 3 can be made slightly conical under certain circumstances; it can also be shaped like a bowl. Instead of the contact strips 10 punctiform contact organs can be provided.

The position change switch can be designed as a self-contained body; he can too have a central ring or another central solid body, so that the ball track like a ball bearing is predetermined.

The possible uses of such a switch are varied; the mode of action is like follows:

When the position change switch is rotated , regardless of its inclination of up to 30 °, the ball initially remains in a "corner" of the pyramid-shaped bulges, with no contact between the ring 1 (conductive) and the electrically conductive strips on the cover plate. With increasing rotation angle the ball 4 comes into a position of unstable equilibrium and finally starts to roll. In doing so, it rolls over the approximately central area of a bulge and forms the desired contact; if the rotation is continued , a contactless interval, a contact, etc. follows again.

It. it is obvious that the choice of deformations in ring 1, the number of contact possibilities and the intervals between them as well as the coupling clock rhythm can be freely selected. It is also not necessary that the contact options are distributed over the entire circumference of the ring 1; rather, it is sufficient if at least two contact points with corresponding intervals are in front of the ring. are seen, are assigned to the corresponding contact points or contact strips on the cover plate.

The production of the position change switch according to the invention is possible in the simplest possible way, since the production of the continuously electrically conductive ring 1, even with the bulges, is just as easy as the production of a cover plate made of non-conductive material, on which electrical contact elements can be printed in the known printing process .
