A mechanism that does not require a power supply to illuminate the LED! By integrating overcurrent protection and switch functions, we reduce the number of components and achieve cost reduction! 【3120】
The "LED Illuminated Switch and Circuit Protector 3120 Series" eliminates the need for separate components such as switches, harnesses, fuse holders, fuses, LEDs, and LED power supplies, reducing the number of parts to create a single product. Additionally, it requires only one panel cutout, achieving cost reduction and miniaturization. As a circuit protector, it does not require fuse replacement. When the overcurrent protection activates, the rocker switch automatically turns OFF. By removing the abnormal load and turning the rocker switch ON again, it can be reused. This also helps minimize downtime. Illumination Status: LED lights up when the rocker switch is ON, and the LED turns off when the rocker switch is OFF. The LED also turns off when the overcurrent protection is activated and the device is in a tripped state. 【Features and Specifications】 - Mechanism that does not require a dedicated power supply for LED illumination - Compliant with international safety standards for medical electrical equipment (EN60601-1) - Also meets UL1077, CSA, VDE, and CQC standards - Suitable for a wide range of applications including machine tools, scientific instruments, construction machinery, vehicles, and motors - Dimensions: D25×W48×H52mm - Products with modules such as auxiliary circuit modules are also available in the lineup.
