Snap action, limit switches are electromechanical devices that recognizes a signal when an input parameter, such as the force of a switch, exceeds a predetermined value. In other words, they detect a physical event. 44505-0440 snap action, limit switches is a miniaturized and robust device, which is specially designed for applications in the demanding areas of railway infrastructures.

Application Field: 44505-0440 snap action, limit switches are used in railway applications such as kinematic boundary measurement and end of track detection. It is also used in safety systems, such as the door switch of a sliding door, in constructions cranes, and for roller shutter controls. Additionally, this device can also be applied in many other industrial applications where a compact design, precise switching, and reliable operation are necessary.

Working Principle: 44505-0440 snap action, limit switches feature a robust plastic housing and are equipped with an actuating element. The actuating element deflects when force is applied, which is then detected by the internal switches. 44505-0440 snap action, limit switch contains two types of switch elements, the Actuator and the Contact bridge. The actuator has two spring elements which contain the force that is needed to actuate the switch. The switch contact functions are determined by the moving contact in the contact bridge. The contacts are a switching element that can be controlled or activated by the application of an external force. The snap action, limit switch will turn on when the actuator is deflected in its mechanical range and the contacts are bridged. The switch will turn off when the Actuator is released, the contacts are open and the force is removed.

44505-0440 snap action, limit switches have a wide range of temperature range capability, from -40 to +85°C, and are available with different actuator heads, mounting options and switch contact functions. The IP (Ingress Protection) ratings are up to IP67, which makes 44505-0440 snap action, limit switches suitable for a variety of applications. These switches are reliable; they have a life expectancy of more than one million switching cycles. Moreover, the 44505-0440 snap action, limit switches are very durable devices which can be installed even in rough and inhospitable environments.

In conclusion, 44505-0440 snap action, limit switches are an ideal choice for a wide range of applications in railway infrastructure and industrial devices. They provide reliable switching with a long life expectancy and a wide operating temperature range. Seen from their advantages and application fields, it’s reasonable to assume that 44505-0440 snap action, limit switches will be more widely used in the near future.
