Main structural description:

The isolation switch consists of a base, insulating support, conductive parts, and operating mechanism. Each pole has two pillars, and each pillar is equipped with a conductive blade at the upper end. The contact points of the two blade contacts are located in the middle of the two pillars. The lower ends of the pillars are equipped with bearing sleeves, which, under the drive of the operating mechanism, can rotate the blade horizontally by 90 degrees to achieve the requirements of opening and closing the switch. The isolation switch is a single pole type, and it can also be connected by a connecting rod to form a linkage pole type. Equipped with CS11 (ungrounded), CS8-6D (single grounded), CS17 (double grounded) manual mechanisms for operation. It is not difficult to see from the above structural introduction that the structure of this isolation switch is reasonable and the operation is flexible and easy; Can be used as a single pole or three pole, easy to install; The contact blade has a large opening distance, ensuring safe and reliable insulation. According to user needs, it can be ungrounded or equipped with single-sided grounding or double grounding.
