What vehicles have inertia switch?
An inertia switch is a safety device found in many vehicles that is designed to detect sudden deceleration or impact, such as in a car accident. When triggered, the inertia switch will automatically shut off the fuel supply to the engine, helping to prevent fires and further damage. Vehicles equipped with inertia switches include cars, trucks, and motorcycles.
What is an Inertia Switch?
An inertia switch is a simple mechanical device that uses a small weight or ball bearing suspended on a spring. In the event of a sudden deceleration or impact, the weight or ball bearing will move, completing an electrical circuit and triggering the switch. This cuts off the fuel supply to the engine, helping to prevent fires and further damage in the event of a collision.
Vehicles with Inertia Switches
Inertia switches are commonly found in the following types of vehicles:
- Cars and light trucks
- Motorcycles
- Boats and personal watercraft
- Recreational vehicles (RVs)
- Heavy machinery and construction equipment
The specific location of the inertia switch can vary by vehicle make and model, but it is typically located near the fuel tank or in the engine compartment.
Importance of Inertia Switches
Inertia switches play a crucial role in vehicle safety by helping to prevent fires and further damage in the event of a collision. By automatically shutting off the fuel supply, the inertia switch can help to minimize the risk of a fire breaking out, which can be a significant hazard in the aftermath of an accident. This feature can be especially important in high-speed collisions or rollovers, where the risk of a fire is elevated.
In addition to their safety benefits, inertia switches can also help to protect the vehicle's electrical system and other components from damage in the event of a sudden deceleration or impact.
Do modern cars have inertia switches?
The widespread adoption of fuel pump inertia switches in modern vehicles stems from a concerted effort to improve vehicle safety, particularly fire risk reduction. While specific inventors aren't widely credited in consumer contexts, automotive engineers developed these devices as a critical solution.
Does my car have an inertia switch?
It is typically located in the rear of the vehicle between the electric fuel pump and its power supply. It can be found on the passenger side in some vehicles, right behind the glove compartment. There should be a picture or wording that indicates the inertia switch is behind the plastic panel.
Which cars have cylinder deactivation?
Cars with cylinder deactivation include various models from General Motors, Honda, Mazda, and Volkswagen. Examples include the Cadillac Escalade, Chevrolet Silverado, Honda Accord, and Mazda CX-5. This technology improves fuel efficiency by shutting off some cylinders during light-load conditions.
General Motors (GM)
Cadillac Escalade, Cadillac CTS, Cadillac ATS, Cadillac XT5, Chevrolet Silverado, Chevrolet Tahoe, Chevrolet Suburban, Chevrolet Impala, Chevrolet Camaro, Chevrolet Corvette, GMC Sierra, and GMC Yukon.

Do Fords still have inertia switches?
Like it or hate it, the Ford/Lincoln Inertia switch was still a great safety feature. But why then would Ford/Lincoln stop using them? The simple answer is, they haven't. Granted modern Ford/Lincoln vehicles do not still use the switch with the red button, however they still utilize a fuel pump shutoff feature.
