Note: 1. A pair of contacts form one circuit; 2. Each section of the delay contact only contains one pair of contacts, and the delay time for the CD10 mechanism is 20MS

4、 Basic parameters (see Table 1)

5、 Institution and characteristics:

The F6 series auxiliary switch is composed of multiple sections, and its internal structure is shown in Figure 1. There are labels on both sides above each section indicating the number of this contact. The diagonal lines in the same section form a pair of normally open (or normally closed) circuits, and the determination of normally open (or normally closed) is displayed by the indicator on the operating shaft. The indicator points to a set of contact limits, indicating that this set is a reliable pair of normally closed contacts (circuits), and the rest are a pair of normally open contacts.
