Snap Action, Limit Switches: 44505-1612 Application Field and Working Principle

Snap action, limit switches are widely used in various industries, including motors, pumps, fans, HVAC systems, appliances, lighting, and more. In today’s market, they are available with a variety of connections and switch types, providing an extensive range of design options. The most common type is 44505-1612, which can be used for both indoor and outdoor applications, and is suitable for use in commercial and residential settings. This article will discuss the application field and working principle of the 44505-1612 snap action, limit switch.

Application Field of 44505-1612

The 44505-1612 snap action, limit switch is designed for use in a variety of applications, such as motors, pumps, fans, HVAC systems, lighting, appliances, and more. It has a wide range of operating temperatures and a high shock and vibration resistance, making it suitable for harsh environments. It is also UL listed and has a variety of terminal options for quick wiring. The 44505-1612 snap action, limit switch is commonly used to detect the presence of an object, rate a change in an environmental condition, and operate a mechanism.

Working Principle of 44505-1612

The 44505-1612 snap action, limit switch is a mechanical switch that uses a spring-loaded actuating lever to make and break electrical contacts. The lever is connected to an electrical contact and a plunger. When the plunger is pressed, the lever is forced to move and make contact with the contact, completing the circuit.

The snap action, limit switch works by two principal actions: the contact arm and flexure. The contact arm is composed of a hollow metal tube with contacts placed on each end so that the contacts are held in place against around the tube. On the other end of the tube is a free-floating metal arm which is spring-loaded and flexes when pressed. This causes the contact to move in a downward direction, into an open position. When the pressure on the contact arm is released, the flexure spring causes it to move outward, bringing the contacts back into contact and completing the circuit.

Conclusion

The 44505-1612 snap action, limit switch has a wide range of application fields: motors, pumps, fans, HVAC systems, lighting, appliances, and more. Its wide operating temperature range and high shock and vibration resistance make it suitable for harsh environments. The snap action, limit switch is designed with a spring-loaded actuating lever and a contact arm and flexure system, which enables it to open and close a circuit with a quick snap action when pressure is applied.
