Latest Patents

One of Nawa's latest patents is for a starter for vehicles. This innovative starter includes an electromagnetic switch that features a first solenoid for pushing out the pinion shaft towards the engine and a second solenoid for opening and closing a main contact that supplies current to the motor. The design ensures that the first and second solenoids are disposed coaxially with the pinion shaft, allowing for efficient operation. Additionally, the plungers in the solenoids are arranged to overlap in the axial direction, preventing operational issues when de-energized.

Another significant patent involves an electromagnetic switch that incorporates contact displacement limiting members. This invention addresses the problem of unreliable operation caused by wear on switch contacts. In this design, the current flow through a coil displaces a plunger axially, enabling current flow via the contacts. The limiting members are strategically placed to prevent the movable contact from being displaced too far, ensuring that it can return to the 'contacts open' position even after repetitive switching operations.
