As a classic masterpiece by Yueqing Tongda in the field of micro switches, the HK-10 High Lifespan 1A/3A Miniature Micro Switch features the core advantages of 'miniature structure, ultra-long life, and precise triggering,' and is specially designed for human-computer interaction devices such as mice and keyboards, as well as small electronic control applications.
Micro Switch Introduction
The HK-10 mouse switch is a miniature, momentary push-button switch designed for office, household, and entry-level gaming mice. Its core positioning focuses on 'high compatibility, high stability, and cost-effectiveness,' catering to multiple needs such as bulk supply for mouse manufacturers and repair or replacement by DIY enthusiasts.
The key advantages are clear and straightforward: First, reliable performance, with high-wear-resistant silver alloy contacts and beryllium copper springs, contact resistance ≤0.03Ω, instant activation without delay or sticking, mechanical lifespan ≥200,000 clicks, fully sealed design to prevent dust and moisture, avoiding common issues like double-click failure; second, strong compatibility, using the industry-standard mini package, allowing it to replace over 90% of conventional mouse switches on the market without modification, making installation convenient; third, comfortable feel, with a moderate actuation force of 0.45-0.6N, quick rebound, reducing fatigue from long-term clicking.
