Dome switches designed for tactile feedback
Tactile switches are mechanical devices that when pressed by the user, provide a bump or click noise in response. Current flow stops when the user stops pressing the switch. “Normally closed” tactile switches work oppositely. Current is turned off when the switch is pushed and flows again when the switch is released. Tactile switches include metal domes in their design that reverse shape under force and make the audible click noise. These typically operate at lower power and current ratings, making these switches well-suited for low voltage devices and systems. Tactile switches usually last longer than other types of mechanical switches because these usually have fewer moving parts. As a result, these offer a cost-effective option compared to some other types of switches. Tactile switches provide tactile feedback to the user when the switch or button makes a contact with the control panel underneath, which is usually a printed circuit board.

Tactile switches include dome switches that are located under a rubber bubble or dome. When the dome switch is pressed, the dome collapses and makes the switch contact. Tactile switches come in a range of sizes and actuator styles and are LED capable. Tactile switches are designed for use in keyboards, keypads, instruments, and interface control-panel applications. These are heavily used in aerospace and aviation, communication, defense, and all electronic instrumentation applications. Dome switches are used in keyboards, keypads, membrane keypads, and various controls high use, ease-of-use, and relatively quiet use are paramount when operated. TE offers a large selection of tactile switches, ranging from miniature surface mount switches to IP rated. Our tactile switches come with dome switches and have different actuator lengths that add a custom feature to fit in every design application.
