Title: Kumio Ozeki: Innovator in Key Switch Technology
Introduction
Kumio Ozeki is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of key switch technology, holding a total of 4 patents. His innovative designs have enhanced the functionality and user experience of key switches in various applications.
Latest Patents
Ozeki's latest patents include a unique key switch design that utilizes a membrane switch actuated by pressure from a movable key member. This design incorporates two coaxial springs connected end-to-end, allowing for a more efficient actuation process. The first spring is held in a partially strained state, requiring an initial force to strain it further. The second spring, which is smaller in diameter and stiffer, applies force to the membrane switch as the key member is pressed. This innovative mechanism allows for long key travel while achieving the actuation force early in the key's displacement. Additionally, Ozeki has developed a double-axis key switch that features a key cap with two key stems. These stems slide into a housing to actuate a pair of switches, correcting any tilting of the key cap for smooth operation.
