2. How did the automotive push button switches become what it is now?

Since the invention of the first button-controlled flashlight in 1898, the evolution of the push button switch took off like a rocket.

Many inventors have explored the many potentials of push button switches on many applications from light switches, doorbells, cameras, radios, telephones, and of course, automobiles.

Its first functions were to lower windows, adjust the driver’s seat, or open and close the ventilator wings on the front doors.

In this era, cars did not start with keys.

You will have to stand outside your vehicle then manually hand-crank the engine until it starts.

Aside from the physical strength required to perform this action, this also imposes serious safety risks such as hand and arm injuries due to the engine backfiring.

Safety became a priority for car manufacturers which led to Henry Leland, the founder of Lincoln and the Cadillac car companies, to commission Charles Kettering to develop a safe and practical way to start a car’s engine.

And in 1912, Charles Kettering finally developed the first electric car starter by just pushing a button.

Thanks to him, starting a car is no longer physical labor or safety risk.

  6. Insert your car key and turn the ignition to the accessory position.
  7. Cut off the head of the key and cover the ignition with tape.
  8. Plug the harnesses to the start-stop button main unit and reconnect the negative cable to the battery.
  9. Test the installation by starting your car and turning off the engine as you would using a car key, test the lights and signals too.
  10. Then determine where you will place the start-stop button so that you can make a hole for it.
  11. Fold up the tabs of the start-stop button so that you can insert it into the hole on the panel.
  12. Then open the tabs of the start top button behind the panel and secure it with glue or tape.
  13. Try to place the transponder ring somewhere hidden.
  14. Secure the wirings and screw back the panels to complete the installation.


  • The start-stop button harness may come with two ignition wires since some cars have two of them.
  • If your car has two ignition wires, ensure you connect them both on the ignition wires from the start-stop button harness.
  • If you only have one ignition wire, you simply have to connect it to one of the ignition wires allocated by the start-stop harness, there’s no need to connect the other one anymore.
  • If your car has two accessory wires and the start-stop button has only one allocated for it, you can combine your car’s accessory wire and connect it.
  • If your car has two constant 12-volt wires, you can also connect them to connect it to the wire assigned for it from the start-stop kit.
  • The last wire should be your ground wire.


  • When you strip the wires, create a hole in between the exposed copper wirings that should make your wiring connection easier.
  • You can use the lead of the voltmeter to make the small holes.
  • Then when you’re connecting the wires of the start-stop button to your car, simply twist and insert them and cover them with electric tape.

19. Will you still need your coded key once you installed the automotive push button switch?

Not necessarily, but one car key should be left permanently in the ignition and it is highly recommended to keep it there and never remove it.

Since you are replacing a part of the car, such as the ignition switch or the horn switch, you may be risking getting your warranty voided which can bring a lot of issues later on.

The warranty outlines what you can and you cannot do to your new car and this is an agreement between you and the carmaker.

Even for old cars, since most of the car insurance policies do not cover damages that are deliberately done to the vehicle or damage caused by car modification or installation of any parts.

However, there is a law that states that car insurance companies must prove that the damage or car failure is because of these before denying any insurance claim.

Despite that, it is still best to read your insurance or warranty coverage to be familiar with what to avoid.

And always look for high-quality switches to ensure that they will not cause any untoward damage to your vehicle.

26. What are the pros and cons of using an automotive push button switch for your vehicle?
