The term "actuator" in German translates to "Stellantrieb." An actuator is a component of a system that is responsible for moving or controlling a mechanism or system, typically by converting a control signal into physical motion. The word "Stellantrieb" is derived from its function, as it combines "stellen," which means to position or set, and "Antrieb," meaning drive or actuator. This reflects the role of an actuator in regulating the position of a part or controlling a system's function.

In contrast, "Schalter" refers to a switch, which does not perform the same role as an actuator. "Regler" translates to controller or regulator, which might oversee the operation of various signals and functions but is not necessarily an actuator itself. "Motor," while it can be a type of actuator, specifically refers to a device that converts electrical energy into mechanical energy. Therefore, "Stellantrieb" accurately captures the broader functionality of an actuator in industrial and technical contexts.
