What Is a Tilt Switch? Everything You Need to Know About Tilt Switches

What is a tilt switch? It’s of the most important parts of devices you use daily.

Tilt switches have been around for decades because they’re simple to produce and don’t require much money. Using a few parts, a tilt switch can be made that will allow devices to turn on whenever they’re positioned a certain way.

Anyone that would like to start making toys and gadgets should learn what tilt switches are because it will be easier to choose one. Depending on what kind of device you’re making, you’ll need a tilt switch to ensure that the device will operate.

So what are tilt switches on a more detailed level? Keep on reading to learn more.


What Is A Tilt Switch?

A tilt switch is an instrument that is used in a variety of devices. Their design is meant to detect whenever a change in orientation or inclination happens. Tilt switches act as sensors and will turn on or off depending on which side they’re tilting towards.

Unlike accelerometers, tilt switches are inexpensive and simple to produce. Accelerometers can go as far as detecting motion and orientation whereas a tilt switch can’t.

Tilt switches are typically made in cylindrical shapes. This creates enough space inside for various parts to allow the switch to operate. 

How Does It Work?

Within the switch lies conductive poles and either a metal ball or mercury. When the switch tilts downwards, the sensor will activate as the conductor contacts the poles.

Different Types of Tilt Switches

All tilt switches operate similarly but are made up of different materials. Today, the most common type of tilt switch is the tilt ball switch. However, mercury was commonly used in the past because it’s dense and doesn’t bounce within a switch.

Tilt Mercury Switch

Instead of using a metal ball to activate the switch, tilt mercury switches use mercury. When the mercury contacts the electrical poles, the switch opens as energy is transferred.

Tilt mercury switches usually have air or inert gas within them to make it easier for the mercury to move within the tube.

Tilt Ball Switch

Over time, tilt switch producers started to move away from mercury tilt switches because of the hazards that come with mercury. They started introducing switches that use a metal ball as a conductor, which is just as effective as mercury.

The main difference between a tilt ball switch and a tilt mercury switch is that the metal ball isn’t hazardous. Besides that, tilt ball switches operate the same. 

Vibration Switch

Vibration switches are some of the most advanced switches because they use vibration to trigger the switches. These switches aren’t directional, so they can be activated no matter what position they’re in.

Whenever a vibration switch is moved, a spring within it will contact the pole and activate the switch. There are different types of vibration switches that allow them to be placed in a variety of devices depending on their use.

Slow vibration switches require a lot more movement to be triggered whereas fast vibration switches will trigger at the slightest of movement.

Pros and Cons of Each Switch

Although tilt switches are meant to do the same thing, each switch has its benefits. For example, tilt ball switches are better than tilt mercury switches when it comes to toys.

Tilt Mercury Switches

Tilt mercury switches, while effective, are toxic and fragile. They can also be impractical if you need to put a switch in something that needs quick triggers.

Mercury tilt switches often operate slowly because they need to wait for the mercury to drop before they can activate.

Tilt Ball Switches 

Tilt ball switches became the standard because they’re much quicker and don’t use much power. They’re suitable for toys and gadgets that people commonly use because they don’t have any hazardous materials.

The downside to tilt ball switches is that the ball can bounce, so these switches can sometimes be inconsistent when activating. It’s common to see devices that use tilt ball switches to flicker on and off before staying on.

Because of the bouncing, anything that vibrates won’t be suitable for a tilt ball switch. Whenever the device turns on, the ball would continue to vibrate, so the device wouldn’t be able to stay on.

Vibration Switches

Vibration switches fall right in the middle of being great for anything while being affordable. Although they’re much more fragile than tilt ball switches, they can also be used in a variety of toys and gadgets.

Because they come in different types, they can be used in almost any device. However, choosing the right vibration switch can be tricky depending on what kind of device you want them in.

If you use a fast vibration switch inside something that shakes a lot, the switch would end up flickering on and off. On the other hand, a slow vibration switch would never turn on if the vibration of a device isn’t strong enough.

Start Learning How to Use a Tilt Switch

Tilt switches are great tools for anyone that’s looking to make devices. From alarms to toys and everything in between, tilt switches are used to operate most devices that we use daily.

Now you should start researching how to use tilt switches for your project now that you have the answer to, “What is a tilt switch?” You’ll be able to make your devices both affordable and functional.
