LED Indication is a reliable and economical way to provide visual indication of status information. Discrete LED indicators can flawlessly identify from simple indication to complex indication. QL332YD is a specific discrete LED indication product, it is mainly used for indication of toggle switches, including toggle switches indicator light, operating position indication light and switch power indication light as well.

QL332YD is a three color LED product that can be used to indicated toggle position of switches. It has a clear illumination, one or two LEDs can be used depending on the requirements like one LED indicates the working state two LEDs indicate the two directions. It can be used for both single throw lever switch and double throw lever switch.

The housing of QL332YD is made of resin and is splash proof. It is a self-operated product with no external power source needed. This product is a RoHS compliant product and has a maximum current of 25mA with a range of 12V to 24V. The typical voltage is 24V.

QL332YD is an ideal choice for commercial, industrial or any indoor applications especially in tight spaces or where environmental concerns make traditional product unsafe. This product is manufactured using SMD process which ensures a small component size and high reliability. Also, this product is extremely cost-efficiency and can be used as an economical alternative to other indication products.

In terms of working principle, when the switch is turned off, the LED indicator will light up to indicate the direction of the pushbutton switch. When the switch is turned on, the LED indicator will not lit up but when the return switch is pressed the LED indicator will lit up to indicate the off position. The LED indicator can withstand a shock of up to 50G and operates within a temperature range of -35℃ to +85℃.

QL332YD has a long life, low power consumption and up to 5 million actuations , and with its SMD process, it offers higher reliability, longer life and bigger cost savings compared to mechanical components. Furthermore, its unique design also makes it an excellent choice for difficult environments, like those in HVAC, automotive or power supply applications.

In conclusion, QL332YD is a discrete LED indication product that is ideal for a variety of applications, such as industrial, commercial and indoor. It is designed to provide reliable information concerning the status of switches and is a cost-effective solution for switch applications where energy savings is desired. The intense light output and extended range offer clear visibility and long-term performance. It requires no external power source and is RoHS compliant, making it a safe and efficient choice for many applications.
