How to solve the problem when the indicator light of the metal button switch does not light up

[JuliaCao]

For metal button switches, during the entire application process, if the light does not light up, this problem needs to be solved immediately to avoid hidden dangers. So how to solve the problem that the indicator light of the metal button switch does not light up? Let’s introduce it to you below.





In different household appliance workplaces, because the circuit line control circuit is very long, the indicator light is not very bright, mostly caused by induced voltage.

1.Insert a small volume size 0.01_0.22UF middle input terminal into the input and output terminal of the distribution line, and then connect a 100k_500k resistor. The actual operation is inconvenient.

2. Add an RC circuit. Many AC contactors also have their electromagnetic coils connected on both sides. Its function is to digest and absorb induced current. This is also a very effective solution.

3. Each display light uses a shielded cable, but it is not very beautiful.

4. Modification of the resistance-capacitance absorber is simple, convenient and cheap.

Therefore, if the indicator light of the metal button switch does not light up, it can be solved in this way.

After reading the above article about ‘How to solve the problem when the indicator light of the metal button switch does not light up’, you will know what is going on next time you encounter it, and you can even solve this problem yourself. You can also consult us for more related questions.
