The small toggle switch group boasts a track record spanning half a century, featuring a robust design, high capacity, and a contact material that is strong against arcing while maintaining high contact reliability.
Developed by Nippon Kaito Kogyo Co., Ltd., double fixed crimping prevents terminal play caused by soldering.
Special silver alloy contacts are strong against arc wear and maintain stable contact resistance.
The switching mechanism is a seesaw type, characterized by long lifespan, robustness, and high capacity.
