There are many types of FAN Shell Moulder on the market. The first thing to consider is the use of FAN Shell Mould. Secondly, it is necessary to consider some factors used by FAN Shell Mould.

(1) Select the rated current value of the Fan Shell MOULD according to the nature of the load. When using FAN Shell MOULD, the start -up current is very large. If the selected FAN Shell Mould cannot bear the impact of the start -up current within the required time, the contact of the Fan Shell Mould will appear. Together or due to arc splashing, the FAN Shell Mould is damaged.

(2) The voltage of the FAN Shell Mould application circuit should be smaller than the rated voltage of Fan Shell Mould.

(3) FAN Shell Mould should pay attention to its insulation resistance for the market power supply. It is best to choose the FAN Shell Mould with a non -metallic operating handle.

(4) Because the good or bad of the contacts of the contacts will directly affect the load of the circuit when connecting the circuit. Therefore, when designing the circuit design, the FAN Shell Mould should be used in the contact resistance; if the small power circuit is designed and necessary, the tentacles of the gold with gold should be selected.

(5) The choice of mechanical life and electrical life of Fan Shell Mould should be determined according to the occasion of use. In the occasion where the switch is frequently turned on, off, and the load is not large, you should focus on its mechanical life when selecting the switch; in the occasion where the switch is suffering from a large power, you should focus on its electrical life when selecting the switch.
