Abstract
A switching device for disconnecting and switching at least one line of a power supply is disclosed. The switching device may be, for example, a residual-current-operated protective device or a combination switch and includes a line-voltage-independent trigger device, a trigger element, such as a trigger relay, associated with the line-voltage-independent trigger device, as well as a line-voltage-dependent trigger device. The line-voltage-dependent trigger device has means for triggering the trigger element that is associated with the line-voltage-independent trigger device. The switching device has a simple construction, a reduced number of components, and also an enhanced functional reliability compared to a conventional switching device.
