The mechanical section features the optimal layout of components and the use of materials with high wear resistance, which provides accurate operation feeling and durability against high-frequent switching up to 5 million times.
Larger breaking capacity of the switch generally requires enlarging the main body. Fuji's control switch, however, has achieved downsizing while increasing the breaking capacity.
This breakthrough has been made possible by optimally designing the cam shape and the angle of the movable contact part for obtaining max. switching speed mechanically.
This allows you to determine the setting values (voltage and current) with allowance.
No up-screw terminal is adopted. It can be quickly wired from the back for the alternate terminal arrangement.
For the body, polycarbonate resin is used, which has a high level of performance among engineering plastics. The material greatly improves strength and resistance against environment (temperature, humidity, vibrations, etc.), which are particularly important for the applications related to heavy electric machinery. The contact and mechanical part are transparent to facilitate checking the contacting part.
In the contact mechanism, the movable contact makes contact with the stationary contact at one point and then gradually increases the contact area while rolling on it. This rolling action minimizes the part exposed to the arc that is generated at the first contact or breaking, thereby maintaining much higher contacting stability than the former product.
