Snap Action Limit Switches

Snap action limit switches are an important component in many electronic systems, providing an effective and reliable means of bringing electric circuits on and off. This type of switch has a wide range of applications in various industries, including those that involve heavy loads, extreme temperatures, and demanding environmental conditions.

Operating Principles

Snap action limit switches operate on the principles of magnetic and mechanical force. When the switch is moved to its active position, a permanent magnet inside the switch interacts with a metal contact, which mechanically moves the switch contacts. When the switch contacts move, an electrical connection is established or broken to control the flow of current.

Design Considerations

Design considerations for snap action limit switches include mounting type, body material, contacts material and function, contact configuration, and contact rating. These design considerations are important for choosing a switch that will match the requirements of its application.

Mounting Type

Snap action limit switches are available with various mounting options, including panel and machine-mountable. Panel mounting is suitable for applications that require the switch to be installed within a cabinet or wall, while machine mountable switches are used for directly mounting to a control panel or machine.

Body Material

The body material of a snap action limit switch will typically be plastic or metal. Plastic housings are best suited for applications that require the switch to be in direct contact with the environment, while metal housings are ideal for applications with high temperatures and high load requirements.

Contacts Material and Function

Snap action limit switches are available with various contact materials, including gold plated contacts, silver plated contacts, aluminum oxide contacts, and ceramic oxide contacts. The contact material will determine the durability of the switch, with ceramic oxide being the most durable contact material. Additionally, contacts may be available in various contact functions, including normally open, normally closed and momentary.

Contact Configuration

Another important design consideration for snap action limit switches is the contact configuration. These switches may be available with single and double pole contacts, allowing for a greater range of functionality. Single pole contacts are ideal for basic applications with limited switching requirements, while double pole contacts are more suited for applications that require more precise control.

Contact Rating

Snap action limit switches are available in various contact ratings, including 1 Amp and 5 Amp. The contact rating will determine the maximum load the switch is rated to handle, and should be considered in order to ensure that the switch is able to handle the requirements of the application.

Conclusion

Snap action limit switches provide an effective and reliable means of controlling electric circuits, with a wide range of applications in various industries. Design considerations, such as mounting type, body material, contact material and function, contact configuration and contact rating should be taken into consideration when choosing a switch for a particular application.
