Why are micro switches used?


Precision and Consistency: Micro switches are designed to provide precise and consistent switching action. They have a well-defined actuation point, which means they reliably change state (from open to closed or vice versa) when a specific force or position is applied, ensuring accuracy in control systems.

Fast Response Time: Micro switches have a quick response time, making them suitable for applications where rapid switching is required. They can respond to changes in force or position almost instantly, making them ideal for applications where timing is critical.

Long Service Life: Micro switches are known for their durability and longevity. They are constructed with high-quality materials and are designed to withstand a large number of actuations without wear and tear. This makes them suitable for applications that require a high cycle life.

Small Size: As the name suggests, micro switches are compact and lightweight. Their small size makes them suitable for applications where space is limited or where a compact design is essential.

Versatility: Micro switches are versatile and can be used in a wide range of applications across different industries. They are commonly used in household appliances (e.g., microwave ovens, refrigerators), automotive systems (e.g., door locks, brake pedals), industrial equipment (e.g., conveyor systems, limit switches), and more.

Snap-Action Mechanism: Micro switches use a snap-action mechanism, which means they have a distinct and rapid change in state when actuated. This mechanism reduces the chances of contact bounce (a temporary, undesirable fluctuation in the electrical contact) and provides reliable switching.

High Precision and Repeatability: Micro switches offer high precision and repeatability in their switching action. This makes them suitable for applications where consistent and accurate control is essential, such as in safety interlocks and limit switches.

Sealing Options: Micro switches are available with various sealing options, including dust-tight and waterproof designs. This makes them suitable for use in environments where exposure to dust, moisture, or contaminants is a concern.

Low Operating Force: Micro switches can be designed with low operating forces, which means they can be easily actuated with minimal physical effort. This feature is advantageous in applications where human interface is involved, such as in the buttons of consumer electronics.

Overall, micro switches are used in a wide range of applications because of their reliability, precision, durability, and versatility, making them a popular choice for various industries and devices.
