Introduction to Snap Action, Limit Switches

Snap action switch, also known as a limit switch, is a class of switches that are actuated by physical pressure applied to a small lever. This type of switch offers high levels of reliability, repeatability, and minimal vibration or noise. These switches are commonly used in a wide range of applications, such as industrial machinery, conveyor belts, and home appliances.

TFCDF 5 ST1840C Application Field and Working Principle

The TFCDF 5 ST1840C is a snap action switch which is suitable for a variety of applications due to its high durability and reliable operation. This snap switch features a type 4X water and dust proof rating, and UL/CSA approval. Its rating is Omron IEC/EN 60947-5-1.The working principle of the TFCDF 5 ST1840C is based on a spring-mounted lever system that is released when a predetermined force is applied to the lever. This physical force causes the lever to move, which in turn flips a set of electrical contacts, completing the circuit and allowing for current to flow. This switch is built around a small plunger and a close tolerance between the plunger tip and the lever. When negative pressure is applied to the plunger, the lever is forced open and when positive pressure is applied, the lever is forced closed. This reaction is consistent for each cycle and is the reason why these switches are so reliable and provide high levels of repeatability. The TFCDF 5 ST1840C can be used as an actuator, a limit switch, or even a safety switch. It can be used in a variety of applications, such as industrial machinery, conveyor belts, and home appliances. It is commonly used to provide feedback to a control system by indicating when a specific amount of pressure has been applied. As the pressure changes, it changes the position of the switch’s contact points, signaling a change in the system.

Conclusion

The TFCDF 5 ST1840C snap action switch is a reliable and durable switch that is suitable for a variety of applications. It features a type 4X water and dust proof rating, and UL/CSA approval. Its working principle is based on a spring-mounted lever system that is released when a predetermined force is applied to the plunger. This switch is commonly used to provide feedback to a control system by indicating when a specific amount of pressure has been applied. It can be used as an actuator, a limit switch, or even a safety switch.
