Essential Gearbox Safety Switch

This small yet vital switch ensures your vehicle’s transmission is securely in neutral or park before starting. It prevents the engine from cranking if the shifter isn’t in the right spot, helping avoid unexpected vehicle movement and protecting your starter system. When you turn the key, the switch checks your gear lever’s position. If it’s not in neutral or park, the system blocks ignition for your safety.
