ALPS SKST series replacement tactile switch

 Key Features and Advantages  

Superior Tactile Feedback: Features a 0.9mm middle-stroke and a high operating force (up to 4N), providing a distinct, confident click that prevents accidental presses—critical for automotive and industrial control panels.

Exceptional Durability: Rated for up to 100,000 cycles mechanical life, ensuring long-term reliability in high-use applications.

Robust Construction: Operating temperature range of -40°C to +85°C with SPST-NO (Off-Mom) circuitry and a compact 8.3mm x 8.3mm footprint.

Versatile Termination: Available with Gull Wing or J-Bend terminals, supporting standard SMT soldering processes.

Application-Ready: Packaged in Tape & Reel (1,500pcs/reel) for automated assembly.

 FAQ 

1. Can this switch directly replace the ALPS SKSTACE010 ?

A pin-to-pin direct replacement. It features an approximately 8.3 × 8.3 mm standard SMD package and a J-lead design, allowing for direct soldering without modifying the PCB layout.

2. How does it feel to use, and what is its lifespan ?

It falls into the "sharp feeling" category, offering distinct tactile feedback. Key specifications include an operating force of 7.0 N, a travel distance of 0.9 mm, 

and a mechanical lifespan of 100,000 cycles—sufficient to cover 95% of real-world application scenarios.

3. Are there any specific things to watch out for during welding ?

This is a critical technical point. Do not clean the switch; prevent flux from seeping in through the top of the switch; 

do not apply flux to the terminals or PCB prior to soldering; and strictly adhere to the recommended temperature profiles for reflow and manual soldering.
