Mini 3*3 Tact Switch

3*3 Tact Switches'  Display

The Operating Principle of Momentary Tact Switch

The working principle of the key Switch is that the two patches are close to each other when the key is pressed, that is, the patch is switched on; When released, the patch detaches, that is, disconnects.

How to solder the 4 legs of a 3*3 light touch switch

1, the multimeter to the diode

2，First measure any two legs in the four corners, determine which two corners are on, which two corners are off

3, press the button, in measuring any two feet, judgment judgment which two corners are on, which two corners are off 4, start to disconnect, press the button on the two feet can be done for the welding of the two angles

According to experience, direct welding can generally be performed as long as the opposite corner

Size: 3.3mm x 3.3mm, this miniaturized design allows it to be easily installed in electronic devices with limited space.

Structure: SMD (Surface Mount) terminal design is commonly used, which not only improves installation convenience but also enhances the reliability and durability of the switch.

Type: Generally a momentary action type, which connects the circuit when pressed and disconnects it when released.

Technical features

Pressing sensation: The Mini 3 × 3 Tact Switch can generate clear tactile feedback (click sensation) during operation, mainly due to its internal structural design technology.

Protection level: Some high-quality mini touch switches have an IP50 protection level, which means they can prevent dust and water from entering to a certain extent, ensuring stability and reliability in various environments.

Customization options: Many manufacturers offer customized button colors, allowing customers to choose the appropriate switch color based on the product's color scheme, enhancing the overall aesthetics of the product.

Application scenarios

Consumer electronics, such as smartphones, tablets, digital cameras, etc., often have strict requirements for the size and weight of switches, and the Mini 3 × 3 Tact Switch perfectly meets these needs.

Automotive electronics: In various control systems inside the car, this small touch switch also plays an important role, such as control buttons for car audio, navigation systems, etc.

Industrial Electronics: In industrial automation and control systems, Mini 3 × 3 Tact Switch is also favored for its reliability and durability.

matters needing attention

Installation: When installing the Mini 3 × 3 Tact Switch, please ensure to follow the manufacturer's installation guidelines to avoid damaging the switch or affecting its functionality.

Maintenance: Although this switch has high durability, it is still necessary to pay attention to keeping it clean and dry during long-term use to extend its service life.
