Abstract: The invention relates to a switch provided with self-cleaning contacts used, in particular for actuating a horn for a steering wheel of a motor vehicle. The inventive switch comprises at least two opposite contacts one of which is movable and touches the opposite contact by means of an actuating element. The self-cleaning of the contacts is carried out by the reciprocal sliding thereof, the contact associated with the actuating element is fixed to a supporting element which is embodied in such a way that it is elastic and fixed to an end, an opposite end being free and moveable. Said invention is characterized in that the supporting element from the fixing side outward has an inclined line with respect to the direction of actuation in the direction of said actuating element, and subsequently in the direction of the free end thereof. A line is also inclined in the direction of the free end thereof with respect to the direction of actuation starting from the actuating element.

Abstract: A ring laser gyro having a triangular-shaped block design (10) includes a cathode (24,26) on each side leg of the triangular-shaped block and one anode (28) on the base leg of the triangular-shaped block. Furthermore, the anode (28) is connected via connecting bores (36,38) to gas reaming bores (30,32) in the corner points of the block in order to pass away ions and electrons of the plasma from mirrors (18,20) arranged in the corner points of the block.

Abstract: A ring laser gyro including two partial gas discharge paths in which by an electrode arrangement an opposite gas discharge is ignited. Outside of the discharge path between the electrodes (24,26) connected to the ignition voltage ion traps (40,42) are provided in order to prevent a gas discharge between those electrodes (FIG. 1).
