product details

As a manufacturer specializing in the R&D and production of tactile push buttons, our 2A3-06 button is an SMD tactile push button tailored for miniaturized electronic devices. With its compact structure and reliable performance, it has become a preferred control component in the consumer electronics and smart hardware sectors.

The 2A3-06 features an SMD package design, with an overall size of only 6.2×3.2×2.5mm. Its compact form factor perfectly fits high-density PCB board layouts, eliminating the need for additional insertion space—allowing devices to retain stable button interaction capabilities even in miniaturized designs. The button body uses a high-temperature resistant engineering plastic housing paired with metal dome contacts: it not only offers excellent anti-aging properties but also adapts to the high-temperature environment of SMT reflow soldering, avoiding deformation or performance degradation during mass assembly.

In terms of core performance, the 2A3-06 boasts a mechanical actuation life of over 10 million cycles, far exceeding industry standards. Even in high-frequency operation devices (e.g., Bluetooth earbud charging cases, smart bracelets), it maintains stable on-off feedback for long periods. Its 160±30gf actuation force balances a lightweight feel with clear pressing feedback: it prevents accidental touches while avoiding user operational fatigue. The silver-plated alloy contacts have a contact resistance as low as 50mΩ, ensuring precise circuit signal transmission and reducing signal loss or poor contact issues.

This button is widely applied in smart wearables, miniature sensors, portable medical detectors, and small home appliance control panels. Its SMD design integrates directly with automated SMT production lines, greatly boosting customers’ assembly efficiency and cutting labor costs. During production, each batch of 2A3-06 undergoes full testing (high-low temperature cycling, vibration, life aging) to ensure mass-product consistency and reliability, easing customers’ after-sales maintenance burdens.

Whether addressing miniature devices’ space constraints or high-frequency use durability needs, the 2A3-06 button delivers solutions via precise design and stable performance. We currently offer small-batch sample testing and customized terminal adaptation services. We welcome industry customers to inquire and collaborate, to jointly elevate the interaction experience of miniature electronic devices.
