Which term describes a situation where a connection is inconsistent due to a 'Wackelkontakt'?

The term that best describes a situation where a connection is inconsistent due to a 'Wackelkontakt' is "unstable connection." A 'Wackelkontakt' refers to a loose or intermittent connection where the electrical contact is not solid, resulting in fluctuations in the connectivity or the signal. This instability can lead to interruptions in the functionality of the device or system relying on that connection. The situation inherently indicates that the connection cannot be relied upon for consistent performance, thus making "unstable connection" the most appropriate term to characterize this situation.

In contrast, terms like "stable connection" or "direct connection" imply reliability and continuity, which do not apply to a scenario marked by inconsistency. "Loose connection" might seem relevant but does not capture the broader implications of fluctuation and unpredictability associated with an unstable connection.
