Product Description

1、 Basic characteristics

Structure: It usually consists of a shell, shrapnel, contacts, control rods, elastic components, and pins. The shell protects the internal components and provides support, the spring provides elastic force, the contacts realize the connection and disconnection of the circuit, the control rod is used for manual operation, the elastic parts increase sensitivity and comfort, and the pins are used to connect the circuit.

Packaging form: SMD packaging is commonly used, suitable for large-scale production and automated soldering.

Operation method: Users can switch the circuit on/off or function by gently touching or pressing the switch button.

2、 Main parameters

Rated voltage: Depending on the specific model, the rated voltage may range from a few volts to several tens of volts, with a common value of 12V DC.

Rated current: It also varies depending on the model, and common rated current values may include 0.5A (some high current models) or 50mA (more common low-power models).

Lifespan: Typically measured by the number of keystrokes, high-quality switches may have a lifespan of hundreds of thousands or even more keystrokes.

3、 Type and Characteristics

Type: Depending on the structure, triggering method, and packaging form, the 3x3 Tactile Switch can be divided into various types, such as top press, side press, side slide, etc.

characteristic:

Clear Tactile sensation: When pressing the button, users can clearly feel the "click" sensation of the button being pressed, which helps to confirm the change in switch status.

Quick response: Due to the fact that the switch action can be triggered by pressing the button, it has the characteristic of quick response.

Low power consumption: suitable for energy-saving design.

Multiple packaging forms: easy to install and use in different electronic devices.

4、 Application Fields

The 3x3 Tactile Switch is widely used in various electronic devices due to its compact size, distinct tactile sensation, and fast response, including but not limited to:

Mobile phones and tablets: used for controlling power switches, volume adjustments, screen brightness adjustments, and other functions.

Computer keyboard: The keyboard keys are touch switches used to trigger keyboard input.

Remote control: used to control household appliances such as television, sound system, air conditioning, etc.

Digital camera: used to control functions such as taking photos and switching modes.

Electronic game controller: used to control the actions and functions of game characters.

Power switches and function selection buttons in household appliances such as televisions, washing machines, refrigerators, etc.

5、 Selection and Precautions

Selection: When choosing a 3x3 Tactile Switch, factors such as the rated voltage, rated current, lifespan, packaging form, and the need for customized colors should be considered. At the same time, reputable suppliers and manufacturers should be selected to ensure product quality and after-sales service.

matters needing attention:

During installation, it should be ensured that all solder joints of the switch are completely cold fixed before touching or shaking to avoid loosening or deformation of the switch.

Avoid frequent pressing of switches to prevent misoperation or malfunction of sensing circuit components.

Pay attention to the protection of the protective sheath of the wire lead on the installation cable of the switch, to avoid scratches that may expose the wire core and cause leakage or short circuit faults due to water vapor infiltration.
