A micro switch, also known as a snap-action switch, is an electrical switch that is operated by very minor physical force, usually a few grams of force. It is a compact and reliable switch used in various applications including home appliances, automobiles, and industrial equipment.
The micro switch comprises of a set of electrical contacts and a mechanism that actuates these contacts. When the actuator is pushed or pulled, it forces the electrical contacts to move from their stationary positions, causing them to either open or close. The mechanism that moves the contacts is usually a spring or a lever, and the force required to move the contacts is pre-set by the manufacturer.
One of the advantages of a micro switch is its versatility. They can be used in a wide range of applications due to their compact size and low actuation force. For instance, they are used in heating and cooling systems, vending machines, and washing machines, to name a few. They are also incorporated into safety equipment, such as elevators, to prevent accidents.
Another advantage of micro switches is their reliability. They have a long lifespan and are able to withstand harsh environments. These switches are designed to operate for millions of cycles, making them very dependable. They also operate over a wide temperature range, making them suitable for use in extreme hot or cold environments.
However, micro switches have some limitations. They are not suitable for applications that require high current or voltage because of their small size. They are also not ideal for applications that require linear motion because they are primarily designed for switch-on and switch-off operations. Additionally, micro switches can be more expensive than other types of switches.
In conclusion, micro switches have been widely used in various industries because of their versatility and reliability. Their small size, low actuation force, and long lifespan make them ideal for use in a wide range of applications. Micro switches are dependable and can withstand harsh environments. Despite their limitations, they remain an essential component in many electrical systems.
