Rated voltage and current: Different models of 2 × 3 Tact switches may have different rated voltage and current values, and users should match them according to specific needs when selecting.
Operating force: refers to the minimum pressure or force required to trigger a switch. Smaller operating force means a more relaxed touch experience.
Contact resistance: refers to the resistance value between the contact points of a switch in the closed state. A smaller contact resistance helps to reduce energy consumption and improve signal transmission efficiency.
Insulation resistance: refers to the resistance value between each contact of a switch in the disconnected state. A higher insulation resistance helps ensure the safety and stability of the circuit.

The 2×3 Tact Switch stands out with its ultra-compact size, and some models come equipped with waterproof and dustproof features. It is perfectly suited for various electronic devices with strict space constraints on components, finding wide application across consumer electronics, medical equipment, automotive electronics, and other sectors. The specific application scenarios are as follows:
This serves as its core application field. It is used as the side shortcut button on smart watches and fitness trackers, enabling screen wake-up or function switching. In TWS Bluetooth headsets and mini Bluetooth remote controls, it acts as a trigger button for operations such as power on/off and mode shifting. Additionally, it can be found on the simple control keys of compact digital cameras and portable audio players. Meanwhile, it is a popular accessory among electronics enthusiasts, ideal for control panels in maker projects like STM32 and ESP32-based circuit boards.
It is compatible with a variety of portable and professional medical devices. For instance, in portable diagnostic equipment such as handheld blood pressure monitors and electronic thermometers, its ultra-thin design fits the compact structure of the devices, and its service life of over 100,000 presses meets long-term usage requirements. On the control panels of precision instruments like electrocardiographs and ultrasonic machines, it delivers stable performance to avoid signal interference and ensure accurate transmission of operation commands. Some special models can also withstand repeated alcohol wiping, adapting to the disinfection needs of medical environments.
It is tailored to the complex operating environment of automobiles. Certain wide-temperature-range models of the 2×3 Tact Switch can be used for menu selection keys on car central control screens and auxiliary buttons for power window lifting. In car key fobs and small on-board controllers, it functions as a trigger component to realize functions such as unlocking and starting. Some waterproof and sealed models can also be applied in battery management units of new energy vehicles, offering dustproof and moisture-proof advantages.
In industrial settings, it can be integrated into PLC (Programmable Logic Controller) devices and small industrial control panels. Models with metal casings also feature electromagnetic interference resistance, making them suitable for complex industrial environments such as those with oil contamination. In the smart home sector, it is widely adopted in waterproof light fixtures, control panels of small smart door locks, and function buttons of mini home appliances. Some models can also be linked with security systems to achieve functions like one-key alarm triggering.
Many small electric toys and remote-controlled toys have extremely high requirements for the size of internal components. The 2×3 Tact Switch can serve as a core control component for toys, such as power buttons and function switching keys. Examples include direction auxiliary buttons for mini remote-controlled cars and action trigger buttons for small electronic dolls. Its reliable triggering performance and cost-effectiveness meet the production and usage needs of toys.
Its common rated load is 50mA DC 12V, suitable for low-power circuits. The maximum contact resistance is typically 50mΩ, and the insulation resistance is no less than 100MΩ to ensure stable signal transmission.
Most standard models work within -30℃ to 85℃, while specialized automotive or industrial-grade variants can endure -40℃ to 85℃, adapting to harsh environmental conditions.
Yes, there are sealed, waterproof, and dustproof models. For harsh environments with liquids, dust, or chemical corrosion, you can choose products with high IP protection ratings (such as IP67/IP68) to ensure reliability.
Common specifications include 180gf and 250gf, with clear clicking feedback when pressed. Some models offer "sharp touch" (short stroke, 0.1-0.3mm) or "soft touch" (longer stroke, 1-2mm) options to meet different tactile needs.
First, check for poor soldering (such as cold solder joints) or loose connections. If the switch is contaminated, wipe the surface with isopropyl alcohol. Persistent unresponsiveness may indicate shrapnel deformation or contact wear, requiring replacement.
Possible causes include foreign objects inside the switch, terminal misalignment, or shrapnel fatigue. Ensure proper installation without excessive pressure, and choose dustproof models for harsh environments.
