1. Clutch Pedal: When the clutch pedal is depressed, it causes a mechanical linkage or an electronic switch to actuate.
2. Interlock Switch: The clutch pedal linkage or switch interacts with the interlock switch, which is located near the gear selector.
3. Neutral Position: When the clutch pedal is depressed, the interlock switch ensures that the gear selector is in the neutral position.
4. Shifting Permission: Once the gear selector is in neutral and the clutch pedal is depressed, the interlock mechanism allows the driver to shift gears.
5. Release of Gear Selector: When the clutch pedal is released, the interlock mechanism locks the gear selector in the selected gear.
6. Override Function: In some vehicles, an override mechanism may allow the driver to shift gears without depressing the clutch pedal. This feature is typically used for specific scenarios, such as starting the engine in gear.
7. Safety Precaution: The interlock mechanism serves as a safety precaution to prevent accidental gear changes and potential damage to the transmission.
It's important to note that the exact mechanism and design of the interlock mechanism may vary depending on the specific vehicle and manufacturer.
