Nyckelläget

Nyckelläget is a Swedish term that translates to the key position and is used in several technical contexts to describe the alignment or setting of a keyed interface. The concept centers on how a key component sits relative to another part in a system, and how this position affects function, fit, and safety.

In mechanical engineering, nyckelläget refers to the orientation of a key and keyway on a shaft and hub. The key transmits torque and maintains angular alignment between parts; the nyckelläget must be specified during design and verified during assembly. Improper nyckelläget can lead to uneven load distribution, wear, or failure of the coupling.

In locksmithing and security contexts, nyckelläget is used to describe the position or configuration of the key within a locking mechanism, influencing operation, fit, and security characteristics. Different nyckelläget settings may determine how readily a lock opens or how resistant it is to tampering.

Etymology and usage: The term is a compound of nyckel (key) and läge (position or state) and is applied where a literal or figurative key position is relevant. Because it spans disciplines, the exact meaning of nyckelläget varies with context and industry.
