The battery delivers a current to the starter of your engine when you turn the key to start it (or push a button). This instructs the engine starter to start the vehicle so you can travel. In the event that your car is in a gear other than neutral or park, the neutral safety switch merely interrupts that current.
Only cars with automatic transmissions are subject to this. In manual gearboxes, the clutch pedal is connected to a similar device. A vehicle cannot start without the clutch pedal being depressed thanks to the clutch neutral switch. Compared to automatic vehicles’ neutral safety switches, this one has a simpler design and costs less to replace. Well, in this article we’ll be discussing answers to questions related to the Neutral safety switch.

What is a neutral safety switch?
The automatic transmission can only be started when it is in Park or Neutral thanks to a safety feature called the neutral safety switch. The neutral safety switch’s main function is to stop the vehicle from starting while it is in gear to avoid an unanticipated forward thrust.
Since the 1950s and the 1980s, nearly all production vehicles with automatic transmissions have been equipped with neutral safety switches. The neutral safety switch is something that most people rarely consider. Unfortunately, if one starts to fail, your car could have a lot of issues.
Although the majority of production vehicles had neutral safety switches by the late 1950s, the SFI Foundation required their usage on manual gearboxes, and they were widely used on all production cars by the early 1980s.
For an automatic transmission, the neutral safety switch might be either inside the transmission case or in the linkage that enables the car to change gears. The engine cannot be started when the transmission is in any gear other than Park or Neutral thanks to this switch.

what are the symptoms of a failing neutral switch?
The engine won’t crank in neutral, however, it will crank in the park
On the other end of the spectrum, a defective neutral safety switch is often to blame when the car starts when the gearbox is in the park but not neutral. The switch may be experiencing an internal component failure in this instance, causing it to activate in one gear but not the other. It might possibly be the result of an electrical issue or that the switch needs to be tightened. If identified early enough, a qualified mechanic can resolve this problem.

Engine cranks in any gear
An internal short circuit in the neutral safety switch can be detected by turning the engine when it is already running and the gearbox is in gear. When this happens, it poses a major safety risk because your car effectively lacks a neutral safety switch. To prevent catastrophic mishaps or injuries, the safety switch in this situation needs to be changed as quickly as possible.
It is wise to get in touch with a qualified specialist, such as the nearby ASE-certified mechanics at Your Mechanic if you encounter any of the aforementioned symptoms or warning signals.

The engine does not crank at all, regardless of the transmission gear
If the engine won’t start at all, an electrical problem with the neutral safety switch is usually to blame. The starting relay is not receiving any power through the neutral safety switch in this situation. As a result, the engine cannot be started by the starter motor. This symptom points to an entirely open electrical circuit within the neutral safety switch, which could be caused by a malfunctioning relay, a blown fuse, or an electrical issue with the switch itself. If the switch is the problem, it must be changed.

The engine will not crank in the park but cranks in neutral
The car’s starter should turn on when the ignition switch is turned on, the automatic gearbox is in the park, or the manual transmission is in neutral and the clutch pedal is depressed. However, if they turn the key while in this situation and the car won’t start, it might be because the clutch pedal or the transmission’s neutral safety switch is broken. A qualified mechanic must personally examine this symptom to identify the best course of action because it could also be caused by a dead battery, a damaged starter, or other component failures.

how do you fix a neutral safety switch?
- The neutral safety switch is not often a simple component to replace due to its position. The majority of people just decide to have their car serviced. This is generally a wise course of action when dealing with electrical issues. However, there are some actions everyone can do to solve an issue.
- A bad neutral safety switch will display many of the same symptoms as a damaged starter or battery. To start correcting a problem, make sure you’ve correctly diagnosed it.
Put the brakes on and start the ignition. Then, rotate the shift selector between the various gears to check if the car can start in any of them. If it performs differently than planned, there is probably a problem with the neutral safety switch. You can also try moving your shifter if your engine won’t start, which is another tip. It can require a small push to return to the proper position if the neutral safety switch has been improperly positioned.
- Once you’ve established that the problem is with the neutral safety switch, you may use your car’s handbook to identify the old one and install a new one. Just keep in mind to first unplug the battery! You can also take your car to a reliable repair if you’re scared to handle your own electrical work.

FAQs
What activates the neutral safety switch?
When the key is turned to the on position, the switch, which functions essentially as a relay, obtains a constant power source. The starter motor receives the current when the key is turned to the “start” position.
What are the signs of a neutral safety switch?
The engine may not crank in park or neutral, may not crank at all, or may crank in any gear as typical symptoms of a broken neutral safety switch.
Where is the neutral safety switch usually located?
It should resemble a cigarette lighter and is often found next to the shifter. Look near the gear shifter if your vehicle has a column switch. The neutral safety switch needs to be screwed onto the transmission’s side.

What problems can a neutral safety switch cause?
When the engine is not in park or neutral, the switch prevents the engine from starting. The risk of starting an automatic vehicle in drive or reverse is eliminated. A defective neutral safety switch, which may be found in the linkage or the transmission box, might harm your car’s engine and transmission permanently.
What is the purpose of a neutral safety switch?
Your car cannot start if the transmission is not in park or neutral thanks to the neutral safety switch, also referred to as the inhibitor switch. When the engine starts, this prevents the automobile from driving forward abruptly.
Can I bypass my neutral safety switch?
The starting motor solenoid receives power directly from the ignition switch when the vehicle is in park and neutral thanks to the neutral safety switch that is included in the transmission selector switch. The selection switch shouldn’t be disregarded because the car can start and run in any gear.
Can you drive a car without a neutral safety switch?
It may be possible to operate a vehicle without a neutral safety switch, but doing so is not advised.
How do you troubleshoot a safety switch?
- Try flipping the switch back to the ON position to reset it.
Unplug all the appliances (if on the power circuit) or turn off all the lights (if on the light circuit) if the switch does not reset.
Switch reset.
After you’ve reset the switch, plug each appliance back in one at a time.
