Latest Patents

Nabetani's latest patents include innovative designs for push button switches. One of his patents describes a push button switch that employs a dome spring switch element mounted in a vertical orientation. This design allows for limited, reciprocating vertical movement of a key top and associated plunger. The actuator, which consists of a coil spring and a pivotally mounted lever, converts the vertical movement of the plunger into a horizontally directed force on the dome spring. This mechanism enables a snap action that completes an electrical connection between the inner and outer contacts of the switch element. Additionally, the design features a rectangular dome spring that enhances force versus displacement characteristics and a flexible support for the inner contacts to reduce wear and impact shock.

Another patent focuses on a keyboard switch and its production process. This push-button switch includes a housing that contains a switch contact spring driven by the vertical movement of a drive rod made from synthetic resin. The design incorporates a contact-driving plate spring portion, which is constructed from a bent portion of a plate spring element. The drive rod is formed through mold processing, allowing for efficient production and reliable operation.
