The relay HKE coil is shown as a long box on the power circuit, if the relay HKE has two coils, draw two long boxes side by side. Also, mark the letter symbol "J" for relay HKE next to the long box or long box. The contacts of relay HKE can be expressed in two ways. One is to draw them immediately on the side of the long box. These expressions are more visual. Another is that, depending on the power circuit connections, each contact must be drawn on a separate control circuit. Usually, the same letter symbol is shown next to the contacts and coils of the same relay HKE respectively, and the contacts are numbered to produce tabular differences. Next, the relay HKE manufacturer will explain the types of relay HKE contacts.
1. When the same type (H type) coil is not inserted, the two contacts are disconnected, and when the plug is inserted, the two contacts are closed. It is represented by the initial "H" in the pinyin of the joint venture.
2. When the same-end (D-type) coil is not inserted, the two contacts are closed, and after insertion, the two contacts are separated. Use the ligature pinyin head "D" to indicate.
3. Deformation (z-shape) contact group type. These contact groups have three existing contacts. That is, the contacts in the middle are the left and right static contacts. When the coil is not inserted, the contact and one static contact are disconnected, and the other static contact is closed. After the coil is inserted, the contact moves, and the original disconnected contact is closed, which becomes the split situation of the original closed, and becomes the switching destination . These contact groups are called transition contacts. It is represented by the pinyin letter "z" of the word "rotate".
