Electronic switch manufacturer: What is a dual-control switch and what problems should be paid attention to when wiring?

In the 1970 s and 1980 s, most people's homes used kerosene lamps as the main mode of lighting. However, by the end of the 20th century, electric lights were everywhere, a small switch and a long and thin wire. Now, when decorating a house, the dual-control switch can provide people with more than one choice. The use of dual-control switches has brought a lot of convenience to everyone's life, such as lighting and other household appliances are gradually using dual-control switches. Today, and electronic switch manufacturers to understand, this convenient life of small tools in the end is what kind.

According to the introduction of the electronic switch manufacturer, the single-control switch is only used to control the on-off function of one place of the lamp; the dual-control switch can be used as two places to control the on-off function of the lamp respectively. The two single switches combined with the dual control switches control two point lights. They are mostly used for the control of one point light switch in two positions, or the control of two point light switches. They are often used in stairwells.

Electronic switch manufacturers said that dual-control switches are often used in the field of lighting. It refers to a switch (ie a pair) with two contacts (normally open and normally closed) at the same time. Usually two dual control switches are used to control a light or other electrical appliance, that is, there can be two switches to control the switching of the light and other electrical appliances. Is a common home building materials accessories.

What to pay attention to when wiring?

1. The installation position of the switch socket: the position of the switch should be kept about 1.3 m-1.5m from the ground. The switch socket cannot be installed after the door of the room, and the switch direction should be consistent. In special places such as bathrooms and kitchens, the installation switch must keep a certain distance from the faucet and gas meter, otherwise there will be safety problems and serious consequences.

2. There is a problem with the switch socket circuit. There are many wires at the switch and the circuit is complicated. Be careful when wiring. General family decoration is to use three-hole socket, so when we are wiring, we must make clear the distribution of ground wire, fire wire and zero line. If the wiring is wrong, it will cause damage to the electrical appliances in the home, the circuit is out of control, and it may also cause a fire.

3. switch connection method

The connection method determines the safe degree of use of the duplex switch. Sometimes the state of the two wires of the bulb interface is uncertain, the zero wire or the live wire; This will lead to the uncertainty of the zero fire at the interface of the bulb, the screw and the base. When the screw is on fire, there is a potential safety hazard.

When wiring, be sure to ensure that as long as the lamp is out, the line on the bubble is not charged, and it is safer to change the bulb. And if the reverse is not safe. In this way, if the light does not turn on when you press the switch at home, do not press the switch back and forth many times, but reset the switch and then replace the bulb. Of course, the sub-switch manufacturers to remind, must also pay attention to ensure that they can not directly contact with the earth, to prevent electric shock.
