PCB Mount Push Switch

8*8MM SPST keyboard tactile button is a unique technology button that can be used in different applications. The button comes with high-quality materials, is compact and easy to install, and has low contact resistance. Its unique features make it an excellent choice for telecommunication devices, remote controls, and input devices like computers. The button is also beneficial in improving the user experience, as it provides a satisfying feeling and sound when pressed. Additionally, the durability and reliability of the button make it an essential tool for designers, engineers, and manufacturers in different industries.

With its diminutive 8*8MM size, this tactile push button is perfect for space - constrained PCB layouts. Its small footprint allows for a high - density arrangement of buttons on the board, enabling the creation of complex control interfaces in a limited area. Structurally, it consists of a button cap, a tactile dome or spring mechanism, and two electrical pins. The button cap is the part that users interact with directly, while the tactile dome/spring provides the characteristic tactile feedback when the button is pressed. The two pins are specifically designed for PCB mounting, either through through - hole or surface - mount technology (SMT), ensuring a secure and reliable connection to the circuit.

Working Principle

As an SPST (Single Pole, Single Throw) switch, it has a simple on - off functionality. When the button is in its natural, unpressed state, the internal electrical contacts are open, and no current flows through the circuit. However, when pressure is applied to the button cap, the tactile dome or spring is compressed, causing the internal contacts to close. This closure creates an electrical connection between the two pins, allowing current to pass through the circuit. Once the pressure on the button is released, the tactile mechanism returns to its original position, opening the contacts and breaking the electrical connection.

Performance and Advantages

The tactile feedback provided by these buttons is a key feature. It gives users a clear and satisfying “click” sensation, which helps in accurately determining whether the button has been successfully pressed. In terms of electrical performance, they typically have a low contact resistance, ensuring efficient current flow when the switch is closed. Their small size also makes them suitable for portable electronics, such as handheld gaming devices, mini - keyboards, and compact synthesizers. Additionally, they are cost - effective, making them a popular choice for mass - produced electronic products.
