Snap action and limit switches are integral components of a variety of applications. The MT-4R27 is one such device, and this article will detail its application field and working principle.

Application Field

The MT-4R27 is specially designed to control the on/off situation of lamps, motors and other electrical appliances in a wide variety of scenarios. With its exceptional electrical performance and equipped with an economy-friendly sealed body, this snap action and limit switch can be used in numerous places:

• Industrial applications: A wide variety of industrial machines, such as injection molding machines, robots, and other equipment, require the MT-4R27 to accurately control the on/off operation.
• Power control: It is commonly used for power control in auto machines, power apparatuses, etc.
• Home furnishing: To enhance the convenience, comfort, and safety of homes and offices, the MT-4R27 is also frequently used in household appliances, such as air conditioners, refrigerators, lighting systems, and so forth.

Working Principle

The MT-4R27 works according to the principle of contactless sensitive switching, meaning that the switch completely avoids the traditional mechanical contact of metallic components. Furthermore, this snap action and limit switch achieves reliable results through its sophisticated design, which includes an updated and powerfully accurate internal circuit.

How does this work? The basic process is as follows:

1. An oscillating coil is inserted directly into the center of the switch, which generates a high-frequency magnetic field when powered from the individual voltage range.
2. The induced force created by this high-frequency magnetic field produces an oscillating current at the dual contacts of the switch.
3. The resulting oscillating current finally produces the desired on/off operation when it reaches the set threshold.

This process is repeated continuously over a fixed period of time and involves minimal to no mechanical part whatsoever, which significantly extends the life expectancy of the switch itself and the device it is applied to, reduces the maintenance and installation of devices, as well as reduces the risk of system failures due to mechanical fault.

Conclusion

The MT-4R27 is a powerful and reliable snap action and limit switch capable of controlling the on/off operation of numerous devices in a wide range of applications. It is specially designed in such a way that it avoids mechanical contact and the associated pitfalls, while it achieves accurate and reliable results with its updated circuit and oscillating coil setup.
