There are many types of sockets on the market. The first consideration is the use of the socket. Secondly, it is necessary to take into account some factors used in the socket and make reasonable use of the socket to maximize the function of your product.
(1) The rated current value of the socket should be selected according to the nature of the load. When using the socket, the starting current is very large. If the selected socket can not withstand the impact of the starting current within the required time, the contact of the socket will arc, causing the socket contacts to be welded together or caused by arc splash. Damage to the socket.
(2) The voltage of the socket application circuit should be less than the rated voltage of the socket.
(3) The socket for the mains power supply should pay attention to its insulation resistance. It is best to use the socket with non-metal operation handle.
(4) Since the socket is connected to the circuit, the quality of the contact will directly affect the load of the circuit. Therefore, sockets with small contact resistance should be used in circuit design; when designing low-power circuits and if necessary, contact sockets with gold should be used.
(5) The mechanical and electrical life of the socket should be selected according to the application. Where the switch is frequently turned on, off, and the load is not large, the mechanical life of the switch should be emphasized when the switch is selected; when the switch is subjected to large power, the electrical life of the switch should be emphasized when selecting the switch.
