Moisture on a tact switch may cause poor contact, key failure or other electrical problems. Dealing with a damp tact switch requires some specific measures to ensure it works properly. Here are some steps to deal with it:

Processing steps:

1. Power off

• Safety first : Before handling a tact switch, make sure the device is powered off to prevent electric shock or further damage to the device.

2. Drying

• Natural air drying : Place the damp touch switch in a dry and ventilated environment and let it dry naturally.
• Use fans : Use fans to increase air circulation and help moisture evaporate faster.
• Silica gel desiccant : Place the touch switch in a sealed container and add silica gel desiccant to absorb moisture.

3. Gentle heating

• Low temperature baking : Use a hair dryer or drying oven to bake the touch switch at low temperature. The temperature should be controlled below 50℃ to avoid overheating and damage to the switch.
• Pay attention to the time : Do not heat for too long, just heat moderately.

4. Cleaning

• Use alcohol : Dip a cotton swab in anhydrous alcohol and gently wipe the surface and inside of the switch. Alcohol can help remove moisture and dirt.
• Clean thoroughly : Make sure all contact points and buttons are cleaned thoroughly.

5. Inspection and testing

• Visual inspection : Check the appearance of the tact switch to confirm there are no water stains and corrosion marks.
• Functional test : Reinstall the switch and test its function after powering on to ensure that the button works properly.

Precaution:

1. Environmental protection

• Moisture-proof environment : Place electronic equipment in a dry, moisture-proof environment to avoid the intrusion of humid air.
• Moisture-proof packaging : Use moisture-proof packaging materials to package and store the touch switch.

2. Sealing protection

• Sealed switch : Choose a touch switch with waterproof and moisture-proof function to enhance its moisture resistance.
• Coating protection : Apply a waterproof coating to the outside of the switch to further improve the waterproof performance.

3. Regular maintenance

• Regular inspection : Check the working status of the switch regularly and deal with any problems promptly.
• Timely replacement : If the switch has been severely damaged, it should be replaced with a new touch switch in time.

Summarize:

When the touch switch is damp, the first step is to cut off the power, then dry it, gently heat it if necessary, clean it with alcohol, and finally inspect and test it. In order to avoid similar problems, preventive measures such as environmental protection, sealing protection and regular maintenance can be taken. These methods can effectively solve and prevent the problem of damp touch switches and ensure the normal operation of the equipment.
