Panel indicators, Pilot lights, more specifically 1.60502.1621000, are aides that are installed inside switchboards so as to be able to depict the electrical status of machinery and alert operators of any malfunction when it arises. They are available in various sizes and styles, given the versatile nature of their application field.

Panel indicators and pilot lights come in bi-colour and tri-colour models. The former primarily has two colours while the latter have three. The three come in either double pole or single pole and have distinct features such as high visibility, sealed lens, momentary switching, and increases in contact ratings. Depending on the model, some may also be anti-vandal indicating ones. They are made in accordance with the standards of IEC 529, EN 60947-1/2 and are widely distributed and installed in machinery such as motor operator panels, lifts and enclosure.

These indicators can receive signal from various sources such as switches, timers, pushbuttons, contactors, motor starters etc. The pilot lights indicate and confirm if the light is in either on or off state to the users. Depending on the requirement of the user, these lights can also be made to be dimmable.

Panel indicators and pilot lights work in accordance with the logic diagram provided. They are connected to the power source and can be said to function as controllers, monitoring the power accordingly as actuations are made on them. When the actuations are made, they send a signal to the processor in the system, which in turn responds with an affirmative/negative voltage signal. This signal in turn activates the sequence of the indicator light. There may be some situations that require the activation of multiple lights in order to reflect the status accurately.

Since indicators and pilot lights are involved in vital tasks that ensure the safety and running of the equipment, it is important that they are maintained in top conditions. Proper installation and checks on a monthly basis go a long way in ensuring a good performance of the devices. In some cases, they may also require frequent replacement during rigorous working hours.

Overall, panel indicators and pilot lights form an integral part of switchboard operations, whether it’s for a factory, a research laboratory, or the household. They are commonly used devices that are used to reliably and safely convey a certain electrical state of any given machinery to the operators. Moreover, they also provide added safety as alerts are triggered when the electrical state changes.
