Description

Command and signalling devices, especially rotary manipulators

technical field

The utility model relates to a command and signal device, in particular a rotary manipulator, which has additional safety functional components, a cylindrical base body and an operating handle rotatably supported in a top cover.

Background technique

Such rotary manipulators are used for command input on so-called human-machine interfaces. In this case, it can be used not only for switching on the control current but also for the power supply circuit by using the rotary actuator as a trip element for the circuit breaker. High demands are placed on such rotary manipulators in terms of longevity, robustness, and tightness of the electrical components with respect to water and dirt. Furthermore, manufacturing should also be as inexpensive and process-reliable as possible.

Command devices are installed in switch panels, control panels, switch cabinet doors or enclosure covers. The command device is usually constructed modularly. This means that the command device consists of an actuating element, a fixing element such as a ring nut or a mounting bracket, and one or more switching elements designed as opening or closing elements. For mounting, the actuating element is usually guided from the front through a hole in the switch plate and mounted from the rear by means of a fixing element. The switching element is mechanically fastened to the actuating element or fixing element by means of screws, hooks, and latches. The electrical connection between the switching element and the control device is realized by connecting terminals.

The rotary manipulator can assume different switch positions by rotating it, for example to switch the motor on or off.

Manipulators need to meet multiple requirements. Therefore, the actuating element should, for example, be simple to install and have a certain attractiveness to the user. But the most important requirement is to switch on the device or put it into a safer state, where it is necessary to ensure that the responsible operator makes this switch state change. Furthermore, it is advantageous that the out-of-service state of the plant is detected in time and from all angles of the plant.
