HSMA-A400-T35M1 application field and working principle

LEDs have become the most preferred form of visual signalling due to the fact that they are compact, energy efficient and generate multiple levels of brightness. This has made them suitable for a range of applications, from warning signals to visual safety indicators. One such LED is the HSMA-A400-T35M1. The HSMA-A400-T35M1 is a discrete LED, also known as an illuminated button, available in both 10mm and 14mm sizes. It is a single-pole, single-throw (SPST) switch, operated by a mechanical plunger and features a variety of mounting options, including ring, back and panel mount. The LED is powered by a DC supply, with an operating voltage of 5V and a switching current of 1A. It is also rated for an operating temperature range of -20C to +80C.The key feature of the HSMA-A400-T35M1 is its dual-colour LED. It supports both red and green colour emission, which can be switched between with a simple push of the button. This LED is commonly used for visual signalling and alerting purposes, for example, in traffic lights and warning systems. Additionally, its dual colour makes it suitable for panel and project management applications.In terms of working principle, the HSMA-A400-T35M1 works in the same way as any other SPST switches. When the plunger is pressed, the contacts close and complete the circuit, allowing current to flow through the LED. This turns the LED on, and when the plunger is released the contacts break and the LED turns off. By taking advantage of this on/off switching, this LED can be used as a visual signalling or alerting indicator.In conclusion, the HSMA-A400-T35M1 is a versatile and energy efficient LED, suitable for a wide range of visual signalling and alerting applications. Its dual-colour LED and mechanical plunger operation makes it an ideal choice for panel and project management applications, while its operating temperature range and switching current offers reliable operation in the most demanding environments.
