Function of the starter safety switch?

The starter safety switch, also known as a neutral safety switch or clutch safety switch, is a safety feature in a vehicle that prevents the engine from starting unless the transmission is in the proper gear (usually park or neutral) or the clutch pedal is fully depressed. This helps to prevent the vehicle from accidentally starting in gear, which could cause the vehicle to lurch forward unexpectedly and potentially cause an accident. The starter safety switch is designed to ensure that the vehicle can only be started safely and under the correct conditions.
