Snap Action, Limit Switches

Snap action, limit switches are electromechanical components that are used to detect position, pressure, and the presence of an object. The GKMB39 is a rotary actuator switch, designed for various industrial applications. It offers reliable and accurate switching performance, high current ratings up to 6.3A, and an adjustable rotation traverse angle of 60°.

Application Field

The GKMB39 applied to robots, electric motors, medical tools, home appliances, industrial control cabinets and other fields. Its major functions include detecting the presence or absence of an object, measuring position or pressure, activating or deactivating motors, and controlling electrical circuits. This type of switch is highly valuable for applications where reliability and accuracy are of the utmost importance.

Working Principle

The mechanical component of the GKMB39 consists of two angularly movable thrust pieces, a dual coil assembly, and a fixed contact piece. When an external force is applied, the thrust pieces translate the application force into a rotational movement and compress the two coils. This, in turn, causes the induction effect in the coil and generates a voltage across the switch output. By controlling the angle of the thrust pieces, the electrical output pulse can be regulated.

In addition, the GKMB39 features two contact pins and two contact blocks, which create electrical connections when the actuator is engaged. This allows the switch to control the flow of electricity and keep it separated from excess electrical load. The contacts and the coils are sealed inside the capacitor-like construction for added protection to ensure reliable operation in harsh industrial conditions. The switch can be operated in temperatures from -25°C to 85°C.

Conclusion

The GKMB39 is a rotary actuator switch designed for reliable switching performance for a wide range of applications. It is constructed with dual coils and contact pins that are sealed within a capacitor-like construction, providing optimal protection and assurance that the switch will work in temperatures ranging from -25°C to 85°C. The adjustable rotation traverse angle allows users to control the electrical output pulse and create effective electrical connections when the actuator is engaged. Snap action limit switches like the GKMB39 are highly valuable in industrial applications where accuracy and reliability are essential.
