44. What is the operation temperature of led switches?

Led switches that are unusually hot to touch may have too much electricity flowing through them or may have bad quality.

If you feel that your led switch is hotter than the room temperature it is best to consult your local and licensed electrician to have it checked.

To confirm if your led switch is abnormally hot, you may refer to the product’s specification or packaging.

Manufacturers would oftentimes include the operation temperature of their led switches in the product page or catalog.

An average led switch can bear from around -20° and up to +55°.

45. What does current limiting resistance in led switch mean?


Figure 29 Different Examples of Resistors

Different examples of resistors for led switch

Led switch current limiting resistor’s purpose is to limit the amount of the current flow in the circuit.

It ensures that the current flow does not exceed the recommended forward current.

resistors have power ratings which are measured in watts.

In general, it has a power rating of 0.125 w up to 1 w.

Remember to select a resistor that is sufficient for the voltage supply of the led switch.

Look for power resistors if you need more than 1 w power rating. But for small push button led lights, maybe the resistor will be connected external.

46. What does contact resistance in led switch mean?

Led switch contact resistance refers to the resistance of the device against the current flow.

A “ductor tester” or ohmmeter is used to test contact resistance and it is measured using the unit of ohmmeters.

The higher the contact resistance is, the lower is the current carrying capacity and higher losses.

47. What does insulation resistance in led switch mean?

Led switch insulation resistance refers to the total resistance of the product’s insulation by applying a range of voltage within minutes.

It is considered one of the electrical safety testing done for electrical mechanisms, devices, or equipment.

48. What does IP rating mean in led switch?

The IP rating is a grading system that determines the degree of protection provided by mechanical casings against dust, dirt, water, etc.

IP stands for ingress protection and is comprised of two numbers that represent different levels of protection.

The beginning number signifies the protection against solid objects while the second number is for protection against liquids.

The higher the IP rating number, the stronger protection the led switch has.

Figure 31 IP Rating Chart

54. What does IK rating in led switch mean?

IK rating or also known as impact protection rating is a classification system that indicates the level of protection provided by electrical equipment enclosures.

A piece of electrical equipment or device will undergo tests to check its strength against mechanical or external impacts.

This system is recognized internationally and many electrical industries are complying with its standards.

It consists of two numbers where the first number represents the strength of impact or energy while the second number refers to the equivalent impact.

The level of protection ranges from 0 to 10 where 10 is the highest level of protection.

Led switch could reach IK09/IK10 grade.

  8. Benzyl butyl phthalate bbp (< 1000 ppm)
  9. Dibutyl phthalate dbp (< 1000 ppm)
  10. Diisobutyl phthalate dibp (< 1000 ppm)

A RoHS compliant led switch means that it has passed the required RoHS testing methods.

The RoHS testing methods include testing by x-ray fluorescence spectroscopy (xrf), gas chromatography and mass spectroscopy (gc/ms), and flame ionization detection (gc/fid)

58. What does reach in led switch mean?

Reach stands for registration, evaluation, authorization, and restriction of chemicals.

This is a regulation that is implemented in the European union.

It started back in december 2006 which affected many industries in the world.

It is considered the most complex legislation, which contains 849 pages and took seven years to complete.

Reach acts as a regulatory body to address the manufacturing and use of chemical substances which has potential health impacts to humans and the environment. Led switch must pass through this test to make sure of your safety.

59. What does CE marking in led switch mean?
