Snap Action, Limit Switches - 44505-1420 Application Field and Working Principle

A snap action switch, also known as a limit switch, is an electrically operated switch. It is designed to be used as a position or limit contact switch in applications such as linear actuators, temperature control circuits, drum switches, and other motor control devices. There are two main types of snap action switches: mechanical and electromechanical. A typical snap action switch is the 44505-1420.

Application Field

The 44505-1420 snap action switch has a wide range of application fields. It is an ideal switch for motor-operated systems and industrial controls. It can be used in such devices as linear and rotary actuators, temperature control circuits, magnetic switches, drum switches, and other motor-operating devices. It can be used to detect the presence of magnetic fields and the opening or closing of a circuit. It can also be used to regulate temperature, as well as to detect the presence of electric current.

Working Principle

The 44505-1420 snap action switch operates using a PTFE, or polytetrafluoroethylene, actuator. The actuator has a snap-acting mechanism that helps to quickly open or close the switch contacts. An electrical signal is applied to the electric circuit and the actuator is actuated. The actuator is forced towards the contact arm and, when the signal is removed, it springs back and the contacts open. The actuator can also open or close other circuits or contacts.

The switch can also be reset manually by pulling the actuator back towards its initial position. This will cause the contacts to return to their original position. This type of resetting is useful in applications where repeated switching is required. For example, in a motor-operated device, the actuator can be reset manually if the motor fails to start, or if it runs too slowly or too quickly.

Advantages of using Snap Action Switches

Snap action switches are highly reliable and durable. They are designed to be used in harsh environments and have a long life span. They are easy to install and maintain. Also, they react quickly to changes in signals. This makes them ideal for applications where fast switching is required. These switches are also very cost-effective.

Conclusion

The 44505-1420 snap action switch is an excellent choice for applications requiring fast, reliable switching. It is easy to install and maintain and works well in harsh environments. Its advantages include durability, reliability, easy installation, and cost-effectiveness.
