Introduction

The 44505-0220 snap action, limit switch is a precision electromechanical device that has a variety of industrial applications. It is highly reliable, cost-effective, and is designed to perform in extreme environmental conditions. It is designed to be used in both open and closed loop control systems and can be used in applications requiring single action, dual action and/or multiple operation points.

Applications

The 44505-0220 is ideal for applications that require a reliable and repeatable electrical switch contact. Typical applications include the detection of object position, end-of-travel, over-travel, and under-travel. It can also be used in hazardous area (Class I and Class II) applications and is divided into two distinct types: the plunger limit switch and the roller limit switch.

Plunger Limit Switches

The plunger limit switch utilizes a plunger that is engaged when a specific position is reached. The plunger is mounted on a stationary bracket and is tensioned against a spring. When the plunger is engaged, it puts pressure on the switch’s contacts and activates them. These switches are designed to be used in applications that require high repeatability and accuracy.

Roller Limit Switches

The roller limit switch utilizes a roller, which is engaged when a specific position is reached. The roller is mounted on a stationary bracket, with a lever attached. When the roller is engaged, it moves the lever and presses against the switch’s contacts, activating them. These switches are designed to be used in applications that require a lower repeatability and accuracy.

Working Principle

The 44505-0220 snap action, limit switch works on the principle of electrical contact activation. When the plunger or roller is engaged, it presses on the switch’s contacts and activates them. This creates an electrical circuit which can then be used to activate other components, such as motors, lights, and other electronic devices.

The switch’s design also allows for a variety of applications. It can be set up to activate with a single action, two actions, or multiple operations. This allows it to be used in a variety of industrial settings, such as factory automation and printing presses.

The switch is also highly resistant to wear, making it a reliable and cost-effective solution for a variety of industrial applications. Its design also allows for easy replacement and maintenance, making it a popular choice for businesses looking for a reliable and cost-effective solution.

Conclusion

The 44505-0220 snap action, limit switch is a highly reliable, cost-effective, and rugged electromechanical switch. It is designed for both open and closed loop control systems and is available in both plunger and roller varieties. It is designed to operate in extreme conditions and is highly resistant to wear. Its design also allows for easy replacement and maintenance, making it an ideal choice for businesses looking for a reliable and cost-effective solution.
