About this item

The 3×6×2.5mm SMD Tactile Switch (Pack of 20) is a compact, surface-mount momentary switch, perfect for space-constrained electronic applications. This pack includes 20 reliable switches featuring a dome-contact design and strong tactile feedback—each click providing satisfying user interaction. Crafted for durability, these switches support multiple operating forces and boast a long mechanical life, making them suitable for frequent use in consumer electronics, instrumentation, and communication devices. The momentary action ensures that the circuit closes only while the button is pressed and opens immediately upon release, ideal for input applications requiring precise control. Their surface-mount (SMD) design enables seamless integration into compact PCBs where vertical space is limited, while still delivering dependable performance. Specifications include a maximum voltage rating of 12V, current rating of 0.05A, contact resistance ≤100mΩ, and insulation resistance ≥100MΩ. Operating characteristics include an actuation force of around 1.56N and a travel stroke of approximately 0.25mm. Designed to withstand operating temperatures from –25°C to +70°C (with storage up to –30°C to +80°C) and carrying a 15-day warranty, they’re a dependable choice for both hobbyists and professionals.
