regler

Regler is a term found in several Germanic languages with different meanings depending on context. In German, Regler is a noun that commonly denotes a regulator or controller—an apparatus or device that maintains a chosen value. It can also refer to a control knob on equipment, such as a volume Regler. Related term Regel means rule, and the verbs regeln mean to regulate or to rule.

In engineering and electronics, a Regler denotes a regulator, as in Spannungsregler (voltage regulator) or Temperaturregler (temperature regulator). In everyday language, a Regler may be the component that adjusts a process or system, or a person who oversees regulatory functions in a mechanical or electronic system.

In Swedish, Norwegian, and Danish, the plural noun regler means rules or regulations. These languages use the term in legal, administrative, and everyday contexts, for example trafiksregler (traffic rules) or säkerhetsregler (safety rules).

As a surname, Regler occurs in some German-speaking regions and may originate from occupational or regulatory associations. It is not associated with a widely recognized place or institution as part of standard reference sources.
