• Use of indicator
• Use of indicator is entirely up to you. It can be fixed to the circuit board and attached to push buttons and switches. These types of indicators are primarily used in circuit board and electronic design. This is because they are relatively small in size compared to other types of indicators, such as car rotation signals.
• Why LED?
• In search of superior performance, LED is the only way forward because it is enhanced by long life and low power consumption. However, there are many other possible reasons, including:　Temperature — LEDs generate much less heat than incandescent or neon lights.　Directional — LEDs emit light in only one direction, reducing the need for additional components such as reflectors. However, this is not the case when LED indicators are used as circuit board signals.　Cost - Generally, LEDs are a cost-effective solution for purchase and operation because of their higher supply compared to standard bulbs and pilot lights.
• Do these indicators come with fasteners? • Each indicator comes with a standard fastening nut, washer and gasket. Quick and easy installation.
