Snap Action, Limit Switches

The application field and working principle of 83274023 are highly relevant to Snap action and limit switches. Snap action and limit switches are contactors designed for reliable electrical switching. They have several main characteristics, including their fast action and the ability to quickly switch as well as maintain contact with electrical devices and circuits. These switches are also commonly used in safety monitoring systems to detect and prevent overloads and overvoltages.

Principle of Operation

Snap action and limit switches work on the same principle of using a moving contactor to switch and make contact with its mating contacts. The typical construction of a snap-action switch is a housing containing a contactor and its associated springs. Therefore, when the contactor moves within its housing, it either opens or closes the contacts depending on how it is designed. It also has a built-in type of limiter that will activate when the contactor reaches a certain point, allowing for a quick and accurate switching action.

Types of Snap Action and Limit Switches

The two general types of snap action and limit switches are classified by their operation. The first type is known as the momentary switch. This type of switch does not have a real-setting position, as it returns to its original state when released. Common examples of momentary switches are those found in elevators and doorbell switches. The second type of switch is known as the maintain switch and has a set position when reverted to, making it more like an on/off type of switch.

Common Applications

Snap action and limit switches can be found in many applications and contexts, both industrial and personal. These switches are used on production and assembly lines, in control panels, and even in gaming and entertainment devices. They are also found in hoists and cranes, as they are extremely reliable at maintaining a stable state while switching under very high loads.

Also, due to the fast action and accuracy of the switch, they are often used as limit and safety switches. For example, they are used in cranes to detect overloads, or in hazardous environments as safety trip switches. The snap action switch also has a long life, making it ideal for many applications that require regular and reliable operation.
