Snap Action, Limit Switches

One of the most commonly used types of limit switches is the 91MCE3-S2 snap action. A snap action switch is one of the most reliable, repeatable, and consistent switch types on the market. The 91MCE3-S2 snap action limit switch is a type of switch that is designed to be used in applications where it is critical that a switch correctly changes state within a certain tolerance and remains in the same state for a long period of time.

Description of the Snap Action Switch

The 91MCE3-S2 snap action switch is a type of device which is designed to be triggered by a specific level of pressure or force. It is designed with a snap action mechanism which takes the form of a ‘click’ when activated by the correct pressure or force. When this occurs, the device changes state.

Applications

This type of switch is usually used in situations where momentary events need to be detected, such as in overcurrent protection, level control, security systems, process control, or machine automation. As the switch has the ability to provide reliable and consistent performance, it is perfect for a wide range of applications, from commercial to industrial, and from residential and medical to military.

Working Principles

The operation of a 91MCE3-S2 snap action switch is relatively simple. It consists of a small plunger which is pushed down when a certain level of pressure or force is applied. When the plunger is pushed down, it trips a mechanical component, which causes the switch to change state. This changes the state of the switch, either allowing an electrical current to flow, or preventing it from flowing.

In the case of an overcurrent protection switch, this hook principle, which changes the state of the switch when a certain level of current is applied, helps protect components within the system by disconnecting the power. This ensures that any excess current is safely diverted away from the system to prevent damage.

Advantages and Disadvantages

The major advantage of the 91MCE3-S2 snap action switch is that it is extremely reliable, repeatable, and consistent. This makes it ideal for a range of applications that require accurate switching. This type of switch also has a fast response time, which is beneficial in applications where quick switching is required.

The main disadvantage of the 91MCE3-S2 snap action switch is that it has a limited range of operation. This means that it is only able to detect a certain amount of pressure or force before it trips and changes its state. Thus, it is not able to detect very small changes in pressure or force. Additionally, as the switch needs to be manually reset after it has tripped, this can result in additional downtime in the event of a failure.

Conclusion

The 91MCE3-S2 snap action switch is a reliable and repeatable switch that is perfect for a range of applications. It is able to detect and trip at a certain amount of pressure or force, thus allowing operators to accurately control the state of the switch. However, due to its limited range of operation, it is not suitable for applications where small changes in pressure or force need to be detected.
