This document describes the features and characteristics of the TACT Switch TM product line. These products come in various types such as sharp feeling, soft feeling, snap-in type, surface mount type, and radial type. They are suitable for various operations in audio equipment, video recorders, communication devices, cameras, in-car components, and home appliances. The products are characterized by low profile, lightweight, durability, and dust-proof structure. They can be installed using reflow soldering.
This document describes the ALPS SKQG series tactile switches, offering two height options (0.8 mm without stem and 1.5 mm with stem) for high‑density mounting. It lists mechanical characteristics such as operating force, travel, and rated voltage, as well as electrical parameters like insulation resistance and voltage proof.
The datasheet also includes recommended soldering conditions for surface‑mount and snap‑in types, packaging details, and environmental performance limits. It is intended for designers and manufacturers who need precise component data for integration into audio, video, communication, and automotive equipment. This manual is written in Chinese.
