Snap action and limit switches are common elements found in many electrical and mechanical applications. The 22SM426-T2 snap action and limit switch is a popular choice for those looking for a reliable, accurate, and responsive switch. This article will discuss the application fields and working principle of the 22SM426-T2 in detail.

Application Fields

The 22SM426-T2 is designed primarily for use as a limit switch in industrial applications. These include providing limit positions for elevators, conveyor drives, material handling equipment, and similar applications. However, the 22SM426-T2 can also be used in a variety of other scenarios such as motor starter limits, door protection, and fire alarm systems. In addition, it can be used as a manual reset switch for electronic equipment.

Operating Principle

The 22SM426-T2 is a snap action electrical switch. This device is actuated when a predetermined force or pressure is applied to the actuator. The release of the pressure causes the internal spring to push the actuator back to its original position, thus creating an off (open) or on (closed) electrical contact. It is designed to handle up to 2 hp at 120 VAC and 4 hp at 220/240 VAC.

The 22SM426-T2 is designed to provide a reliable and accurate switch operation. This is enabled by its hermetically sealed construction and double-break contacts. It also has a ratio of mechanical displacement to electrical contact travel of 1:50, allowing for precise positioning and control. The 22SM426-T2 can handle up to 200,000 mechanical operations, and provides a maximum total contact resistance of less than 100 milliohms.

Conclusion

In conclusion, the 22SM426-T2 is a reliable and accurate snap action and limit switch designed primarily for industrial applications. It is designed with a hermetically sealed construction and double-break contacts, allowing it to handle up to 200,000 mechanical operations. The 1:50 ratio of mechanical displacement to electrical contact travel also ensures precise positioning and control. The 22SM426-T2 can also be used in a variety of other applications, including motor starter limits, door protection, fire alarm systems, and electronic equipment reset switching.
