1. Cause of the problem
After using the electrical switch for a long time, due to the influence of external factors such as moisture and corrosion, the surface of the Silver contacts for the Switch will oxidize, resulting in poor electrical contact and causing use problems.
2. Countermeasures
1. Use alcohol smearing method: First, after turning off the power of the appliance, use cotton to dip in an appropriate amount of alcohol and gently wipe the surface of the switch until all the dirt and oxides on the surface are wiped off.
2. Use sandpaper cleaning method: First disassemble the electrical switch, then use fine sandpaper to gently rub the surface of the switch until the surface becomes bright, and then clean it with a brush after use.
3. Use pencil lead scrubbing method: The method of use is very simple. Grind the pencil lead in the air, then smear it back and forth on the surface of the electrical switch contact several times, and then turn on the switch. The contact is like new.
3. Preventive measures
1. Avoid a humid environment: Try to avoid a humid environment when using electrical switches at home, open windows regularly for ventilation, and do not soak the electrical switch in water during ventilation.
2. Regular maintenance: Regular maintenance of electrical switches, such as cleaning and lubrication, can effectively reduce the occurrence of poor contact with electrical switches.
3. Quality assurance: When purchasing electrical switches, try to choose brands with good quality to avoid oxidation problems during use.
4. summary
The above are solutions and preventive measures for the problem of poor Silver contacts for Switches caused by the oxidation of electrical switches. In life, we must maintain regular maintenance of electrical switches, avoid humid environments, and choose electrical switches with guaranteed quality. Only in this way can electrical switches be durable and bring more convenience and peace of mind to our family life.
