With switch socket, usually on the basis of the Type 86 five-hole panel socket to add a pair of switches.
With switch socket
A socket with a switch is equivalent to a combination of socket and switch. In use, switches usually have two functions.
1. The switch is used to control the lamp, and there is no direct connection between the switch and the socket in use.
2. Switch control socket to power on and off.
Switch socket wiring
Today mainly talk about the correct use of switch control socket, often people will say that sockets with switches, in use is easier to damage, usually after the switch is damaged, the socket is dead.
The rated current of the Type 86 switch socket is usually 10A, and it can be determined that the current between the socket and the switch can pass 10A.
However, the switch does not have the ability to turn on and off 10A current, and the switch only has a small current on and off.
The same is true of sockets, although the socket can pass 10A current, but does not have the ability to plug in, unplug and disconnect 10A current.
Take the example of a microwave oven to properly use a switch socket
microwave oven
The microwave plug is plugged into an outlet with a switch. Press the switch and the microwave oven will power on.
When the microwave oven is energized, the current is small, and the microwave oven only has a large current when it is heated.
The heating use of the microwave oven must be controlled by a switch on the microwave oven, and when it is necessary to stop,
It is absolutely forbidden to use the switch on the socket to power off
。 You must use a switch on the microwave oven to stop heating, or wait until the set time to automatically stop heating and the heating stops before turning off the switch on the socket.
The switch on the socket is only responsible for powering up and powering off the microwave oven instead of plugging and unplugging. The heating start and stop of the microwave oven must be controlled by a switch on the microwave oven.
When the microwave oven is heated, the current is very large, and if the switch of the socket is powered off, it will produce a large arc, which is easy to burn the contacts of the switch and affect the service life of the switch. The switch of the microwave oven does not directly control the large current, but controls the thyristor in the circuit board, and the thyristor turns on and off the large current. The switch of the microwave oven is a small current control large current.
The same is true for induction cookers and rice cookers in use, and the switch on the socket is only responsible for powering up the electrical appliances. The use of induction cookers and rice cookers must be controlled by the start and stop buttons of the appliance itself. The switch on the socket can be turned off when the appliance is stopped.
The switch on the socket is equivalent to a knife switch, the contact is copper metal, when the current is turned on and off, the arc spark generated is relatively large, it is very easy to burn out, burn the black copper contact, affect the contact surface of the contact, produce contact resistance, and it is easy to produce sparks when the current is large, affecting the life. The switch on the socket is not suitable for large current on and off, only suitable for small current on and off.
