What are Clik Domes?
If you’ve ever used a keyboard, remote control, or any other device with buttons, you’ve likely encountered tactile dome switches. These small switches are commonly used in electronics to provide a tactile response when pressed. They offer a variety of benefits, including durability, reliability, and ease of use.
Tactile dome switches are also known as snap dome switches, because they use a small metal dome to make contact when pressed. This dome is typically made of stainless steel or other metals, and can be coated with a conductive material like Nickle, Gold or Silver. When the dome is pressed, it collapses and makes contact with a circuit board or other electrical component, completing the circuit and registering the button press.
Because of their small size and simple design, tactile dome switches are ideal for use in a wide range of electronic devices. They can be found in everything from TV remotes to medical equipment, and are often used in applications where reliability and durability are key. With their long lifespan and ease of use, tactile dome switches are an important part of modern electronics design.
Overview
Tactile dome switches are a type of momentary switch that are used in a wide variety of electronic devices, including remote controls, keyboards, and game controllers. They are known for their tactile feedback, which provides a tactile response sensation when the switch is pressed.
These switches consist of a metal dome that is placed on top of a circuit PET/FPC/PCB. When the dome is pressed, it inverts and makes contact with the responding contacts, completing the circuit and sending a signal to the device.
The dome then returns to its original shape, ready for the next actuation.
Tactile dome switches come in a range of shapes and sizes, and can be made from different materials such as stainless steel or nickel-plated phosphor bronze.
One of the key advantages of tactile dome switches is their long lifespan. They can typically withstand millions of cycles, making them a reliable choice for devices that are used frequently. They also have a low profile, which makes them suitable for devices with limited space.
Overall, tactile dome switches are a versatile and reliable component that are used in a wide range of electronic devices.
Mechanical Properties
When it comes to tactile dome switches, there are several mechanical properties that are important to consider. Here are some of the key factors to keep in mind:
Actuation Force
Actuation force refers to the amount of pressure required to activate the switch. Tactile dome switches typically have a low actuation force, which means that they can be activated with a light touch. This can be beneficial for users who need to type or input data quickly and efficiently.
Tactile Feedback
Tactile feedback is the sensation that the switch provides when it is activated. Tactile dome switches are known for their crisp, responsive feedback. When the switch is pressed, the metal dome collapses and then quickly returns to its original shape, providing a satisfying tactile sensation. This feedback can be important for users who need to know that their input has been registered.
Durability
Durability is a key consideration for any switch, and tactile dome switches are no exception. These switches are known for their long lifespan, with some models rated for millions of cycles. This durability can be important for applications where the switch will be used frequently or in harsh environments.
Overall, tactile dome switches offer a number of mechanical advantages that make them a popular choice for a wide range of applications. Whether you need a switch for a keyboard, a control panel, or another type of device, tactile dome switches are a reliable and efficient choice.
Applications
Clik Domes are widely used in many industrial and commercial enviroments, they can be found in Membrane Switchs, Dome Arrays used in conjunction with different types of circuits, PET/FPC/PCB. They can also be found as stand alone switch contacts in various devices which have a mechnaical HMI, but providing the actual switch function and tactile feedback.
The Range of Clik Domes
S-Range
The S-Range is a 4 leg version and is probably by far the most commonly used. Extremely high durability available in various sizes and froce ranges. Its design makes it an ideal choice on single layer or double sided circuits.
S-Range come in the option of Non Dimple and Dimple types, this dimple plays apart dependant on the type of responding circuit foot print being used.
The center hole option alllows for backlighting with an LED placed on the circuit.
R-Range are low profile, and are available with a feet option to increase travel and hence tactile responsitivity.
OL-Range offer a space bar approach for larger area keys, and likewise a hole option for LEDs.
R-Range
T-Range
OL-Range
Packing Options
Domes can be supplied loose in bags or on T&R for SMD placement.
Most dome sizes can be loaded onto a Tape and Reel for automated or other placement options.
Tape & Reel Package has each snap dome sealed in a socket on a continued tape and packed on a reel, so it can be used with traditional automated placement equipment.
Now we can make four-leg snap dome, triangle snap dome, and circle snap domes in the Tape & Reel package, because this shape enables the correct dome orientation to match the target footprint on the circuits.
