Key functions & working principle

Working Principle	1. Position Functions: '- "Off": Disconnects all power to the engine and accessories (cuts electrical flow to ECU and starter).
	- "Accessory": Powers cab electronics (lights, radio) without activating engine systems. - "Run": Supplies power to the ECU, fuel injectors, and ignition system (prepares engine for startup). - "Start": Sends a momentary signal to the starter solenoid, which engages the starter motor to crank the engine. Once the engine starts, releasing the switch returns it to "Run."
	2. Safety Interlock: The switch only delivers the "Start" signal if the ECU confirms safety interlocks (e.g., seat belt fastened, parking brake applied) are active – preventing accidental movement.
Core Functions	1. Engine Activation: Initiates the starter sequence to crank and start the engine – the primary control for equipment operation.
	2. Power Mode Control: Manages power distribution to accessories and engine systems (avoids draining the battery when equipment is idle).
	3. Safety Protection: Works with interlock systems to prevent unsafe startup (critical for operator and job site safety).
	4. Durability: Withstands harsh conditions to ensure reliable startup – minimizes downtime in time-sensitive construction/mining tasks.
