Snap action, limit switches are devices used in industrial and domestic environments to detect when a limit has been reached, preventing any further movement or action. The 5SE218 is a type of limit switch that utilizes snap action technology to achieve this function.

What is a snap action, limit switch?

A snap action, limit switch is a device that uses a mechanical linkages to detect when a motion or other type of operation has been stopped or reached. These switches are commonly used in industrial machinery, communication systems, lighting system and other types of electrical systems. This type of switch contains two basic parts: an actuator and a contact block. The actuator is the physical mechanism that moves when a limit is reached and can range from a toggle lever to a plunger. The contact block is responsible for the electrical connection and contains an array of contacts that are either set to open or closed when the actuator activates.

The 5SE218 application field and working principle

The 5SE218 is a snap action, limit switch designed for industrial control applications such as material handling, automation and robotics. This switch is designed with a high-temperature thermoplastic housing and is impact and shock resistant. It also features a heavy-duty actuator mechanism that is resistant to wear. The 5SE218 is actuated manually by pushing down on the plunger and is available with an optional spring return.

The 5SE218 is a single pole, double throw (SPDT) with both normally open and normally closed contact blocks. The contact blocks are made of silver alloy, which provides excellent electrical contact and long life. When the plunger is actuated, it pushes down on a spring-loaded mechanism that creates a snap action, pushing the contacts open or closed depending on the position of the actuator. The 5SE218 is also available with an optional SPDT position switch.

Conclusion

The 5SE218 snap action, limit switch is a high-quality and reliable device that can be used in a variety of industrial applications. It is designed with a heavy-duty actuator mechanism and is available with an optional position switch. Its impact and shock resistant thermoplastic housing provide excellent protection against external factors. Its silver alloy contacts ensure good electrical performance and extended life. With these features, the 5SE218 is an ideal choice for controlling industrial machinery.
