The purpose of this article is to explain the IAR3F1900 pushbutton switch’s application field and working principle. The IAR3F1900 is a type of pushbutton switch with a sliding mechanism, designed to make a connection when pushed. It is a single-pole double-throw (SPDT) switch that can be operated by pressing the pushbutton up or down. The switching action is achieved by a spring-loaded plunger which moves contacts up and down, connecting one circuit and breaking another. The IAR3F1900 is used in a variety of applications, ranging from consumer electronics, to industrial and commercial control systems.

The IAR3F1900 features a wide range of operating forces ranging from 0.14N to 0.48N. It can support up to two amp current and can be used to control equipment from a distance using a wireless remote control. The contacts are protected with a dust cover, allowing operation in severe environments. The pushbutton switch is available in a variety of styles, including a touch sensitive model, and a rotary actuator model.

The IAR3F1900 has a wide range of operation temperature with a min-max range of -20℃~+85℃. Additional scratch-resistant coating aids in long term operations. It also has a long life cycle of up to one million cycles, ensuring reliable performance. The switch is particularly suitable for those applications where reliability cannot be compromised.

The IAR3F1900 works by pressing the pushbutton switch down or up, depending on the model. The integrated, spring-loaded plunger moves the contacts, making or breaking the connection. The connection is kept constant as long as the switch is held down, and is released when the switch is released. This method of operation is highly reliable and is particularly suitable for applications where momentary contact is needed.

When it comes to customization possibilities, the IAR3F1900 is quite flexible. For instance, it can be adjusted for a wide range of forces. Its unique design also leaves room for multiple actuators, such as touch sensitive, rotary, and membrane actuators. Furthermore, the switch’s shape and size can be tailored to meet customer requirements and several different mounting options are available as well.

In summary, the IAR3F1900 pushbutton switch is an excellent choice for a variety of applications. Its reliable operating mechanism, long life cycle, numerous customization options, and broad range of operating temperatures make it a suitable solution for many applications.
