What Are Panel Indicators?

What Are Panel Indicators?

Distributor Alan Butcher Components helps to explain.

 

Panel indicators are optoelectronic devices which emit light to show the operating condition of a machine or appliance.  Manufacturers and distributors use various terminologies for this type of product which can be confusing when trying to source an item, particularly on-line:

 

  • Signal lamps
  • Signal lights
  • Indicator lights
  • Indicators
  • Panel indicators
  • Pilot lights

 

Essentially, the above terms all describe a light used on electrical equipment to indicate that the device is working.

The light sources for indicators are now primarily LEDs (light-emitting diodes) or Neon lamps.  Both are robust and durable so what are some of the advantages and disadvantages of each?

 

  • LEDs are bright, have a longer operational life and very low power consumption. However, they are initially more expensive than a neon alternative.
  • Neon lamps are particularly suited to higher voltage applications of 110 volt AC, 220 volt AC, and DC applications in excess of 90 volts. This makes neons a much easier option for indicating mains operation. However, they have a limited brightness and less colour variables than LEDs. In addition, they don’t last as long as LEDs.

Applications

LED and Neon indicator applications are varied and include:

  • Fridges and freezers
  • Cookers, ovens and ranges
  • Machine tools
  • Medical equipment
  • Garden tools
  • HVACs
  • Cleaning products such as vacuum cleaners/pressure washers/steam cleaners
  • Coffee machines
  • Vending machines
  • Irons
  • Control panels

 

Panel signal lamps come in various sizes, shapes and colours.  Switch-size indicators are often used alongside rocker switches and push buttons on a control panel.  This ensures uniformity in the visual appearance of an application.
