Product characteristics
High reliability:
1.Precise,flexible and smooth in switch transfer;
2.Service life up to more than 8,000 times;
3.Strong in anti-interference ability without outward interference;
4.Beautiful in outer appearance,small in volume and light in weight;
5.As required,front operation,side operation,inside-cabinet operation or outside-cabinetoperation are provided.
Good safety performance:
In the SKG1 series load isolation switches,a composite contact is mounted and a spring loaded accumulator,an instantaneous release ac-celerating mechanism,momentary make and break and a double break contact structure are adopted in the operation mechanism,which has nothing to do with the intensity of the operation handle,thus improving extremely the electric and the mechanical performances.
