Stoppläget

Stoppläget is a term used in Swedish technical language to denote the stop position of a mechanism or device where motion is halted. The stop position serves as a defined reference point for positioning, calibration, and safe operation. The word combines stoppa (to stop) and läget (the position), reflecting its role as the point at which movement ends.

Applications and usage: In mechanical engineering, Stoppläget refers to the end-of-travel position of an actuator, valve, slider, or similar component. It is often established by a physical stop, a detent, or a limit switch to prevent further motion and to provide a known reference for control systems. In robotics and automation, reliably defining Stoppläget is essential for homing procedures, repeatable cycles, and predictable startup behavior. In consumer devices, the concept appears as end-of-travel limits or resting positions for joysticks, knobs, and sliders.

Design considerations: Important factors include precise tolerances, wear resistance of contacting surfaces, the durability of the stopping element, and reliable sensing of Stoppläget by the control system. In safety-critical equipment, redundancy may be implemented with dual limit switches or optical sensors to improve reliability.

Variations and related concepts: The term is often used interchangeably with limit stop, end stop, or home position in different contexts. In maintenance manuals and calibration procedures, Stoppläget is explicitly defined to ensure consistent operation.
