LED circuit board indicators are small, light-emitting components used to indicate the operation or “state” of a circuit. Normally, these indicators are used in a wide variety of applications including medical or industrial equipment, automotive, and home appliances. LED circuit board indicators are often used along with switches, relays, motors, and other components to create various operational states.
LEDs are preferred to other types of indicators because they are energy efficient, durable, and require very little power to operate. Additionally, they come in different sizes and colors, making them easy to customize. In most cases, LEDs are connected to the circuit board through wires and soldered onto the board. LEDs can also come in larger sizes and with more elaborate designs. These types of LEDs can help improve the aesthetic appearance of a device.
