F9-36I/W type auxiliary switchDetailed product description：

The F9-36I/W auxiliary switch is suitable for controlling the closing, opening, interlocking, and signal circuits of high-voltage switch operating mechanisms, as well as various high-voltage switch cabinets. It can also be used as a conversion or combination switch.

2、 Usage conditions:
1. Altitude not exceeding 3000M;
The temperature of the surrounding medium should not exceed+40 ℃ and should not be lower than -40 ℃;
At a temperature of 25 ℃, the relative humidity of the air should not exceed 90%;
4. Vibration acceleration not exceeding 15m/s2;
There is no explosion hazard in the surrounding medium, no conductive dust, no damage to insulation, and no gas environment that can corrode metals

3、 Model meaning:


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

5、 Institution and characteristics:
The F9 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.

The contact between the dynamic and static contacts of this series of auxiliary switches is made by a circular sliding crimping method. The pressure between the hoes is generated by a separately set compression spring, which is non-conductive and far away from the heating part. The movable hinge joint of the static contact is connected by bare copper wire welding, making the current performance more reliable
The delayed quick action mechanism is flexible in operation, precise in timing, and switches quickly. The quick action mechanism only starts to drive the moving contact to rotate quickly after the active arm rotates to 65 ° -75 ° until the end point, and can reliably stay at the end position. Therefore, it meets the requirements of delay and quick action.
