Es ist ein Positionsregler vorgesehen, der eine Stellstange umfaßt, die ein erstes Ende mit mindestens drei flachen Seiten und ein zweites Ende aufweist. Eine einstellbare Komponente steht mit dem zweiten Ende der Stellstange in Wechselwirkung und ist durch die Umdrehung der Stellstange einstellbar. Ein Satz von Blattfedern steht mit einer ersten der mindestens drei flachen Seiten der Stellstange in Wechselwirkung, um eine unerwünschte Bewegung innerhalb des Positionsreglers zu verhindern. Der Positionsregler findet eine spezifische Anwendung bei der Durchführung von Einstellvorgängen in Druckmaschinen.

The limit switch device has small overall dimensions due to a close-packed arrangement of the set (30) of step-down gears, which are assembled on at least two pins to obtain very high step-down ratios. Inside the casing, made up of a base (10) and of a cover (80), there is an intermediate plate (60) with a flat surface (62) on which there are at least two projecting couplers (52, 46) to drive operating components (70, 72 ...) that can be quickly assembled in different combinations by using seats designed for this purpose. The toothed wheels of such an assembly (30) can mate each other by means of hubs having polygonal joints (23, 34, 39), which are discrete or integral with other elements such as the said couplers, and which make the assembling easier.

The worm gear limit switch device has very small overall dimensions due to a close-packed arrangement of a set (45) of step-down gears, assembled on two pins (26, 30) ; by means of which is possible to obtain very high final step-down ratios. Inside the casing made up of a base (10) and of a cover (80), there is an intermediate plate (50) with a flat surface (52), on which there is a bush (38) for the movement intake of a variety of components that can be quickly mounted in by using previously prepared seats. The toothed wheels of said set (45) of gears can be assembled by means of hubs with polygonal shape (23, 29, 37) which make the assembling easier.

The worm gear limit switch device has a very small overall dimensions due to a close-packed arrangement of the set (55) of step-down gears, which are assembled on two parallel pins (26, 30). The device utilizes as operation components a cam sleeve (70) combined with a group of microswitches (72) separated each other, of which the cam sleeve can be directly coupled on the upper portion (49) of a small shaft (48) which project over an intermediate plate (60) on which there is a socle (66) for fixing said microswitches.
