Benefits of Mini Switch
High Sensitivity
Mini switches have a small contact gap and low actuation force, resulting in high sensitivity. They can quickly respond to external mechanical forces, achieving rapid on-off control of the circuit.
High Reliability
The contacts of mini switches are made of precious metal materials, providing good conductivity and corrosion resistance. At the same time, their housings are often made of high-strength, wear-resistant materials, capable of withstanding harsh usage environments, ensuring long-term stable operation of the switch.
Small Size and Light Weight
Mini switches are compact and lightweight, making them easy to install and carry.
Structure of Mini Switch
Plunger or Actuator
The plunger or actuator is the part of the microswitch that experiences external force. This component is what initiates the switch's operation. Depending on the design, plungers can vary in shape and size, tailored to specific applications. From button types to roller designs, each serves the purpose of translating physical pressure into electrical action.
Cover
The cover of a microswitch is designed to protect its internal components from dust, moisture, and external contaminants. This protective casing is crucial in maintaining the switch's reliability and longevity, especially in harsh environments.
Moving Piece
Inside the microswitch, the moving piece, often linked to the actuator, is responsible for the switch's action. This component moves in response to external force, making or breaking the electrical connection.
Support
The support structure within a microswitch holds all the components in place, ensuring that the moving piece can operate smoothly and precisely. This base is the backbone of the switch, providing stability and alignment for accurate functionality.
NC Terminal
The Normally Closed (NC) terminal is one of the switch's contact points. In its default state, the circuit between the NC terminal and the common terminal is complete, allowing current to flow. When the switch is activated, this connection is broken.
NO Terminal
Conversely, the Normally Open (NO) terminal is disconnected in the switch's default state. It only establishes a circuit with the common terminal when the switch is actuated, allowing current to pass through.
Contact
The contact is where the electrical connection is made or broken within the switch. High-quality materials, such as gold or silver alloys, are often used for contacts to ensure reliable conductivity and resistance to corrosion.
Moving Arm
The moving arm connects the moving piece to the contact. It translates the motion of the actuator into the opening or closing of the electrical circuit. The precision of the moving arm's operation is vital for the accurate performance of the microswitch.
Types of Mini Switch
Miniature Micro Switches
Even smaller than sub-miniature types, miniature micro switches are used in extremely space-constrained environments. Despite their small size, they maintain high reliability and precision. Common applications include small household appliances, office equipment, and compact electronic devices.
Roller Design Micro Switches
Roller design micro switches feature a roller at the end of the lever. This design minimizes wear and tear on the actuator itself and allows for smooth, consistent actuation as objects pass over the roller. They are ideal for use in applications where a moving object activates the switch, such as in conveyor systems or in door mechanisms.
Push-Button Micro Switches
These switches are activated by a push-button actuator. They are straightforward to use and are commonly found in consumer electronics and machinery as start or stop buttons. Push-button micro switches are also often used in emergency equipment, where a quick and easy method of activation is crucial.
