In a multi-stage switch with a shared actuator and at least two switching components for making contact, the switching components are arranged side by side above contacts on a circuit board which bridge them when they are switched on. The actuator for the switch is fitted above the switching components to move in such a way that the switching components respond in succession when the actuator is depressed. Such a multi-stage switch can be economically manufactured using simple means, has universal application, and is easily to operate, largely maintenance-free and reliable.

A manual control device with a control stick (joystick) whose output signal is proportional to the angular deflection of the control stick has transducers that step the output signal in such a way that the manual control device imitates or simulates the switching behaviour of a N-stage manual control device. For that purpose, analog or digital electronic means associate with the output signal of the manual control device, depending on its value, one among N different voltage values, whose number and potential difference may be predetermined. The advantages of an analog manual control device (few mechanical components, cheap production) are thus combined with the advantages of a N-stage manual control device (adjustment information for the user, wider field of application in industrial control processes).

Bei einem Verfahren zur Kanalabfrage durch den Empfänger einer Fernwirkanlage wird das Squelch-Signal des HF-Teils des Empfängers auf Vorliegen eines HF-Signals auf dem eingestellten Kanal abgefragt und erst danach in Abhängigkeit vom Ergebnis dieser Abfrage weitere Schalt- oder Auswertvorgänge des Empfängers veranlaßt. Dadurch wird die üblicherweise verwendete Kanalsuche durch Abfragen der empfangenen Telegrammadressen wesentlich beschleunigt, ohne daß ein zusätzlicher Aufwand erforderlich ist, da das Squelch-Signal bei den üblicherweise verwendeten Standardbausteinen, aus denen HF-Empfänger aufgebaut sind, ohnehin zur Verfügung steht.
摘要:
In order to generate a stepped deviation characteristic, a manual control appliance with a control lever (20) has a ratchet arrangement designed as a shaped part (10) whose surface which cooperates with the control lever has the shape of a spherical segment covered with a grid of ratchet grooves (RX, RY). In particular the bottom of the housing (30) of the manual control appliance is designed as a single piece which is such a shaped part. This shaped part may be produced by most simple means, may be easily fitted into the manual control appliance and is reliable in operation.

摘要:
In a manual controller with a control lever mounted in a housing and held in a bearing so as to swivel around two orthogonal axes around a fixed point, the bearing is designed as an elastomer joint whose elastic restoring force is directed towards the zero position of the control lever from all deflected positions of the control lever. This elastomer joint ensures an accurate bearing and remplaces by a single piece several mechanical components of previous devices. By appropriate dimensioning, additional restoring elements for returning the control lever to its zero position may either be completely dispensed with or have smaller dimensions. In addition, rubber or a corresponding plastic material for the elastomer joint also prevents humidity from entering the housing and thus has an additional sealing function. The elastomer joint, as an easy-to-produce, single-piece component, thus replaces several bearing, restoring and sealing components required in the state-of-the-art, or simplifies their design and production.
