Step 1 First determine the live wire and the neutral wire, both of which carry different voltages and currents.
Step 2 Connect the live wire of the power cord to the normally closed contact of the key switch, and in the same way, connect the neutral wire of the power cord to the negative pole of the switch, so that the first closure can be formed.
Step 3 Power-on test, press the button on whether it can turn on the electrical appliance, and whether pressing the off button can turn off the electrical appliance.
1. During routine maintenance and inspection of key switches, we should pay attention to whether the key switches have quality problems such as brittleness, deterioration of flexibility, or cracking due to aging. Many materials of the key switch themselves have the effect of dustproof and electricity isolation, and attention should be paid to maintenance during daily use. People can start from the power isolation material of the key switch to eliminate more hidden dangers of consumption.
2. Due to the high flexibility of the key switch, be careful not to squeeze too hard when pressing. Since the principle is the same whether it is the control button on the fine instrument or the button on the simple one, it is assumed that pressing or tapping with great force will reduce the flexibility of the key switch itself.
3. If you find that the key switch has abnormal operation, remember not to suspend the disassembly without authorization. In the absence of a professional maintenance environment, many high-end electrical products need to be unpacked in a dust-isolated environment. It has the effect of conducting electricity, which is a very risky method, and it is easy to further damage the switch. Therefore, the inspection and maintenance of the illuminated key switch must be stopped in a special environment.

Dongguan Ou Gao Electronics Co., Ltd. is a professional company dedicated to high-quality electronic and electrical switches and sockets. The company has developed and accumulated for many years. Rich marketing experience and many mature high-quality products. Switch products mainly include key switches. The key switch mainly refers to the light touch key switch, also known as the light touch switch. The key switch is an electronic switch, which belongs to the category of electronic components. When used, the switch function is closed and turned on by applying pressure to the operating direction of the switch to meet the conditions of the operating force. When the pressure is removed, the switch is turned off. Force changes to achieve on-off.
The key switch has the advantages of small contact resistance load, accurate operating force error, and diversified specifications, and has been widely used in electronic equipment and white goods. Because of the environmental conditions of the key switch (elastic force with pressure less than 2 times/environmental temperature and humidity conditions and electrical performance), large equipment and high-load buttons are directly replaced by conductive rubber or dome switch hardware shrapnel, such as medical equipment, TV. machine remote control, etc.
