Latest Patents

One of his latest patents is a trigger switch for power tools. This invention includes a case with a switching mechanism inside, which is open on one side. A cover fits inside the opening of the case to close it, while a trigger is arranged outside the case to operate the switching mechanism through a sliding operation via a plunger. The design features an engaging depression on the inner wall surface of the case and a shoulder on the cover's outer peripheral end. An engaging projection extends outward from the shoulder's side surface, allowing it to engage with the depression. Additionally, a joint groove formed by the inner wall surface and the shoulder is filled with an adhesive agent.

Another patent involves a trigger switch that includes fixed contacts forming main contacts in series, functioning as a switch to supply power to a motor. The design incorporates slide plate parts connected to the fixed contacts and movable contacts within an actuator that interlocks with an operation part. When the operation part is drawn, the actuator moves forward, causing the movable contact to make electric contact with the fixed contact, supplying power to the motor. Simultaneously, the auxiliary contact bridges over the slide plate parts to ensure no potential exists between the movable and fixed contacts. Releasing the operation part separates the movable contact from the fixed contact, breaking the connection with the slide plate part.
