Snap Action, Limit Switches - TFCFF5ST155AC application field and working principle

A snap action, limit switch is a type of control device designed to transfer on or off an electrical circuit when triggered. TFCFF5ST155AC is one such type of switch. It has been widely used in industries, including commercial and residential applications. This article will discuss the application field and working principle of the TFCFF5ST155AC snap action limit switch.

Application Field

The TFCFF5ST155AC snap action limit switch can be used in a variety of industrial applications. It is mainly used as a safety switch in areas where machinery is exposed to the possibility of overload or excess current. It is also commonly used in control panels, machine automation, and medical engineering. The switch has also been extensively used in elevators and wheelchair lifts.

The switch is also used in a variety of other applications such as industrial security devices, automated door mechanisms, light switches, as well as vending machines and ATMs.

Working Principle

The working principle of the TFCFF5ST155AC snap action limit switch is based on the operation of a mechanical lever assembly. The mechanical lever assembly is operated by a switch arm, which is in contact with a contact which is either normally open or normally closed. When the switch arm is actuated and brought into contact with the contact, the circuit is temporarily closed and an electrical connection is established between the switch and the contact. This electrical connection is then utilized to control and transfer on or off an electrical circuit.

The actuation of the switch arm is verified by a plunger action and a snap action is initiated when the lever is released back. The snap action is created by a small release spring which causes the lever to snap back into its normal position. This snap action mechanism is then utilized for on- or off-action.

Conclusion

The TFCFF5ST155AC snap action limit switch is a reliable and efficient control device that has been widely used in a variety of industrial applications. Its working principle is based on the operation of a mechanical lever assembly and a snap action is initiated when the lever is released back. The switch is designed to transfer on or off an electrical circuit when triggered, making it an ideal choice for areas where machinery is exposed to the possibility of overload or excess current.
