Model and its meaning

Structure and its characteristics
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 brake blade horizontally by 90 degrees to meet the requirements of opening and closing the switch. The isolation switch is a single pole type, and the three poles can also be connected through a connecting rod to form a three pole type that can be linked together. Equipped with CSII or CS17 manual mechanism for operation. CS17 is used for isolating switches with grounding devices. It is not difficult to see from the above structural introduction that this isolation switch has a reasonable structure and flexible operation as needed; 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.
