SS-5-FT

Snap action limit switches are devices used to maintain a position or sense when a certain action takes place. They were originally designed for use in industrial settings, but are now commonly found in everyday devices such as kitchen appliances, toys, and security systems. Snap action limit switches are typically actuated by a mechanical force or contact, like a hinge or plunger, and have a reset mechanism to return them to the original position. They are usually classified as electromechanical switches because they typically use an electric current to activate the mechanism.

The SS-5-FT is a type of snap action limit switch that is used in automation and process control applications. It is a low-cost, general-purpose switch with a snap action that can provide a reliable closing or opening point. The SS-5-FT switch is designed to monitor the position or presence of objects or to detect when an event occurs in a system. It can be used to detect when a machine tool is in a certain position, or when objects enter or exit a predetermined area. It can also be used with other components such as sensors and controllers to create an automation system.

Working Principle

The SS-5-FT snap action limit switch operates on a reed switch principle. When a magnetic field is detected by the switch, the reed switch is actuated and the switch triggers. The switch contacts then remain in the open or closed position until the magnetic field is removed or the reset mechanism is activated.

The SS-5-FT switch consists of a sealed housing with a energy source, a primary magnetic element, a reed switch, a reset coil, and a secondary type of coil or spring. When the primary element is magnetized, electrical current is induced in the reed switch, causing it to switch. When the magnetic field is removed, the reed switch resets and the contacts return to the normal position.

The SS-5-FT switch is designed to be mechanically operated and is not suitable for continuous duty operation. It is also not suitable for use in applications where switching electrical loads with voltages greater than 30 VAC or DC is required. It can be used in applications where momentary switching voltages up to 30 VAC or DC may be present.

Conclusion

The SS-5-FT snap action limit switch is a low cost, reliable switch that can be used in a wide range of automation and process control applications. It is designed to monitor the position or presence of objects or to detect when an event occurs in a system. It operates on a reed switch principle and is not suitable for continuous duty operation.
