The assembly serving as the control mechanism for an engine’s electrical system activates essential components, including the starter motor and ignition system. This device, commonly found in vehicles, enables the operator to initiate and terminate the engine’s operation. As an example, rotating the key in this mechanism from the “off” position to “start” engages the starter motor, initiating the combustion process.
Its significance lies in its role as the primary point of control for the vehicle’s engine. Functioning as an on/off switch, it also often incorporates additional positions to power auxiliary systems without running the engine. Historically, earlier iterations of this component were simpler mechanical devices, while modern versions may incorporate electronic security features such as immobilizers or coded key recognition to deter theft and enhance vehicle security.
