Snap Action, Limit Switches: MS118405 Application Field and Working Principle

MS118405 is a snap action, limit switch, also known as a selector switch. It is used for a wide range of electrical control applications, such as pumping equipment, material handling systems, motors, and other various electrical control systems. The MS118405 snap action, limit switch has a long service life, and is designed with the flexibility to be used in many different applications, making it a popular choice for many customers.

Design and Construction

The MS118405 snap action, limit switch is designed and constructed with a few key features that make it stand out from other competing products. To begin, the MS118405 switch has a momentary contact-type trigger and a large contact-block contact that is designed to provide reliable switching. This contact-block is composed of NitrileButadiene Rubber (NBR) material and uses copper-based contacts which are resistant to corrosion, shock, and vibration. In addition, the contacts in the MS118405 are designed to ensure performance during operation over a wide range of temperature ranges from -25°C to 70°C. The switch is encased in an IP67 rated housing for moisture, dust, oil and solvent protection, making this model ideal for outdoor applications.

Working Principle

The MS118405 Snap Action Limit Switch works on a trigger mechanism. Its design centers around a press-to-operate type switch. When the trigger is pressed, it pushes the actuator into contact with a switch operative plate. This plate is designed to open and close the circuit when the contact-block is engaged and disengaged. The actuator is designed to spring back when released and re-engage the contact-block.

The MS118405 snap action, limit switch also features adjustable contacts that allow the life of the switch to be optimized and to suit the application needs. Additionally, the switch has adjustable pre-travel distances that are adjustable within a range of 0.5 to 1 mm. This allows the switch to be customized to a user’s particular needs and ensures reliable operation in the intended application. The adjustable contacts, coupled with the adjustable pre-travel distances, make the MS118405 snap action, limit switch one of the most versatile switch solutions available.

Applications

As previously mentioned, the MS118405 snap action, limit switch is a great choice for many applications due to its versatile design and features. This switch can be used in a variety of applications including, but not limited to, pumping equipment, material handling systems, motors and other electrical control systems. In pump systems, the MS118405 is used to monitor the pressurized liquid systems and provide power to operate associated components. In addition, the MS118405 can be used for applications that require contact-biased motion or tensioned travel, such as in material conveying systems or material handling systems. This is due to the adjustable pre-travel distances, which allow the limits of the upper and lower stop points to be set to the output of the conveyor or material handling system. This is just one example of how versatile the MS118405 snap action, limit switch truly is.

Conclusion

The MS118405 snap action, limit switch is a versatile and reliable solution for a wide range of electrical control applications. Its IP67 rated housing protects the components and internals from moisture, dust, oil and solvents, making it perfect for outdoor applications. The adjustable pre-travel distances and adjustable contacts allow the user to customize the switch to suit their particular needs. This makes it a great solution for applications such as pumps, material handling systems, motors, and other electrical control systems. The MS118405 snap action, limit switch is designed to give users the reliable and consistent performance they need.
