Ignition switch for Terex Lorain LCD 150

The ignition switch 4202975 acts as the main control point for the engine ignition and shutdown processes in the machine. It activates the electrical circuits required for engine cranking and supplies power to auxiliary systems, such as instrumentation and lighting, when the key is turned to the run position. By managing these electrical pathways, the component ensures that the machine starts and stops according to the operator's input.

This component is specifically designed for the Terex Lorain LCD 150 crane. It features multiple positions, including off, accessory, run, and start, to facilitate the correct sequence of operation for the engine and connected electronic systems. The switch provides the necessary electrical contact to handle starting currents and operational power loads required by the crane's electrical architecture. It serves as a security interface to manage access to the machine's starting system and helps protect internal electronic components from improper power sequences during startup.
