Bio invention relates to a gyro-operated electrical switch, in particular such a switch .Switch in a rapidly rotating projectile © performs a switching process when the projectile has reached its The angular position and / or orientation suddenly changes, for example when serving.

BAD ORiQ (NAL 0098 26/1127

There are switches that "bsi Ysräii." the movement of a projectile is confirmed. In one known switch is a nagaetiscix arrested Element arranged, in one of the other Schaltor one of a spring held Maase, Biese known switch each have certain distributions -.> but are expensive. The object of the invention *; boatsiit in creation of a switch, do you? the most insignificant merits of the two known switch, but is cheaper to manufacture.

To solve this problem, the invention provides a gyro-operated electrical Schaltsr, which is characterized by a double frustoconical member, one part of which is reversed compared to the other part of the member, an annular body which is movably mounted on the double cone-shaped üliei xrei and when the Switch as a whole engages the constriction between the two parts of the double frustoconical member, the double frustoconical member forming one contact of the switch and a second contact at a small distance from one end of the double truncated cone-shaped member, electrically isolated from it and so dimensioned

is that the ring body bridges the two contacts and thereby closes the switch when the hanging body as a result of a change in the torque ε exerted on the switch, a precision movement of the DoppelkegalstiimpfförniigQ limb auafülart.

The inner surface of the bing body preferably forms a cutting edge that is attached to the Έ-iB attacks both parts of the double-cone-shaped link * To achieve a good electrical contact, the ring body, the double frustoconical Link and the second contact is gold-plated. The second contact can have the shape of a flat disc, the one at one end of the switch at right angles to the Longitudinal axis of the double frustoconical member narrow " arranges is * The double frustoconical limb can be provided in one piece with a base plate, the diameter of which is essentially that of the second contact corresponds to, or the frustoconical Link can be attached to such a base plate. The wide contact and the base plate are with With the help of a spacer ring arranged at a distance from one another and electrically isolated from one another.

Such a switch can be operated by a Hara, a Be umechlocsen plastic or the like,

Implementation examples of practice are provided below described on the basis of the drawing * Show in this

On the double frustoconical member 1 is a Ring 9 mounted so that it can move freely, the inner surface of which

forms a cutting edge. In order to achieve good electrical contact, the limb 1, the plate 2, the Plate 7 and the Hing 9 should be gold-plated. The electrical connections 10 and 11 are on the plate 7 and the Plate 2 provided.

The ring is shown in full lines in its normal position. Connections 10 and 11 are isolated from each other,

For example, if the switch is on a floor When the projectile is rotating, the cutting edge strives at the constriction between the two parts attacking the frustoconical limb because of the Bing 9 takes up the twist of the remaining parts of the switch. The double frustoconical member around which the Hing 9 circles, forms one contact of the switch The other contact of the switch is formed by the plate, which is formed by the insulators 5 and 6 of the Limb · 1 is isolated.

When the switch rotates around an axis, din with it coincides with its own longitudinal axis or is parallel to it, the ring 9 remains in a

axis essentially normal position. With a request, however, on the ring 9 via its contact point with the frustoconical member 1 a Force exerted that causes the hang around a Axis that rotates across its diameter extends its point of contact with the frustoconical member.

In this case, the Hing 9 assumes the position indicated by dashed lines in the drawing. Now will smell the member 1 and the plate 7 and thereby «wipe the connections 10 and 11 established a connection so that an electrical circuit is closed.

But even if the slowdown is negligible is small, however the orientation of the axis of rotation is changed, the ring seeks its rotation and the to continue the original direction of travel so that he also closes the switch.
