Snap Action, Limit Switches - SSLE12 (BB) Application Field and Working Principle

Snap action limit switches, including the SSLE12 (BB) model, are used in an array of application fields ranging from simple industrial function control to much more sophisticated tasks. These special switches are designed to be both cost effective and to provide reliable operation, making them a common choice for many systems. In this article, we’ll take a look at the design and working principles of the SSLE12 (BB) snap action switch in order to understand its uses and benefits.

Design for Performance

The SSLE12 (BB) series of snap action switches is designed and constructed with a variety of features that make it a highly functional and reliable component. The switch has a stainless steel enclosure with a built-in external cam plate to permit mounting in multiple directions. For enhanced performance, the SSLE12 (BB) also features dual contact points with finger-action roller technology, a switch toggle designed to guarantee 1,000,000 operations before replacement and a built-in safety wire heade.

The switch also features a brass body that is resistant to temperatures up to 167°F and is designed to protect against shock and vibration. The SSLE12 (BB) is also highly flexible, offering either mechanical or electrical operation with an optional manual reset or dual pressure operation. Depending on the model and specific requirements, other features such as an integral switch, EMIL protection or a variety of contact lengths can be provided.

Working Principle

The SSLE12 (BB) snap action limit switch works on a simple lever principle. When the switch is activated, the built-in cam plate applies a pressure to the switch toggle. This pressure is then transferred to the dual contacts of the switch, thus triggering the switch to close and thus completing the circuit. This triggering action is designed to be precise and repeatable, making it suitable for precision applications.

Once activated, the switch latches and the contacts are opened again when it is reset. This reset process is either done manually, by pushing the reset button, or with a dual pressure system that applies a pressure to both sides of the switch. The SSLE12 (BB) is designed to withstand thousands of cycles with no deterioration in performance.

Applications

The SSLE12 (BB) snap action limit switch can be used in a variety of application fields. These include factory automation, such as machine control, conveyor systems and robotics. This switch is also used in medical devices, in display lighting fixtures, fire alarm systems, and in electronic circuit protection applications. Industrial uses include machine tooling, material handling, packaging, and applications involving complex machinery.

The SSLE12 (BB) switch is also commonly used in laboratory and industrial equipment, such as in refrigeration systems, power equipment, elevation control, door and gate control systems, and HVAC systems. The high performance, flexible design and cost effectiveness of the SSLE12 (BB) make it the ideal switch solution for many different applications.

Conclusion

The SSLE12 (BB) snap action switch is a highly flexible and reliable limit switch that is suitable for use in many different applications. Its design ensures durability and performance, making it ideal for precision control. The wide range of possible applications makes the SSLE12 (BB) a suitable choice for many different types of systems.
