Although you may not know it, you likely use tactile domes every single day, whether you’re unlocking your car with a remote or playing video games with your kids. These small metal switches can be found in all types of electronics, and they’re intended to make your life easier by providing thousands upon thousands of uses without fail.
Closing the Circuit
The idea of tactile dome switches is fairly simple – the dome design is created so that the top of the dome rests against the outer rim or edge of the button or control (think about the “unlock” button on your car remote). When pressed, the dome collapses and makes contact with a secondary pathway in the circuit board, thereby “closing” the circuit and sending the signal for the electronics to do what they were designed to do. These circuit boards can have fairly simple designs, from a car remote or video game controller, to complex designs such as medical equipment and aviation controls.
Finding the Right Tactile Domes
While your car remote may only have one or two tactile domes, some applications require multiple domes. Our Peel-N-Place dome arrays come preloaded with pressure sensitive adhesive, making them easy to place into your chosen electronics for optimal efficiency. If your circuit board calls for 50 domes, or 150, we can create an array that meets your needs. Above all, we want you to have controls and switches that work perfectly throughout the lifetime of your product.
Millions of Life Cycles
When using a tactile switch, you may be thinking that at some point the dome will give out and the control will no longer work. While that is a possibility, domes such as our GX-Series are designed to exceed five million life cycles. That means, if you press a button with a GX-Series dome 50 times a day, then the button will keep functioning for 100,000 days. It’s fairly unlikely that you’ll exhaust a dome’s life cycle, even though it’s kept in use for several years. With things such as aviation and medical switch controls, the technology will likely be upgraded, which means that you’ll be replacing the equipment sooner rather than later, and that means new tactile domes!
