What is a Micro Switch?
A micro switch is a small, sensitive switch that requires minimal force to activate. It typically has two contacts - Normally Open (NO) and Normally Closed (NC) - which are connected via a snap-action switching mechanism1. The switch toggles between states when a certain amount of force is applied to the actuator, which is usually a lever or button.
How Does a Micro Switch Work?
The operation of a micro switch is all about the movement of the actuator. When force is applied to the actuator, it triggers the internal spring mechanism, causing the contacts to either connect or disconnect. This snap action mechanism is what gives the micro switch its distinctive clicking sound when activated.
Types of Micro Switches
Micro switches come in various types, each designed for specific applications. Some of the most common types include:
Standard Micro Switches: These are the most common type, used in home appliances, industrial equipment, and more.
Subminiature Micro Switches: These are smaller versions used in compact devices.
Ultra Subminiature Micro Switches: These are the smallest micro switches, used in very small devices or where space is extremely limited.
Applications of Micro Switches
Micro switches are used in a wide range of applications due to their reliability and durability. They are commonly found in home appliances, industrial equipment, and safety devices. For example, they can be used in door interlocks, vending machines, elevators, and electric power tools.
Conclusion
Micro switches are a small but essential component in many devices. Their reliability, durability, and versatility make them a popular choice for many applications. Whether you’re designing a new product or repairing an old one, understanding how micro switches work can help you make the most of this versatile component.
Remember, when choosing a micro switch, it’s important to consider the requirements of your specific application, including the necessary force, the type of actuator, and the required durability. With a wide range of micro switches available on the market23, you’re sure to find one that fits your needs.
