1 Fast on-off control
The micro switch achieves instantaneous action through a small contact interval and a quick-action mechanism, and can complete the on-off of the circuit within a few milliseconds, with an extremely fast response speed. Its working principle is that the external force acts on the drive rod or reed to trigger the instantaneous switching of the contacts, which is suitable for scenes that require high-frequency operation.
2 Safety protection and limit detection
In industrial equipment and household appliances, micro switches are often used as safety protection elements. For example:
Microwave oven: Detect the closed state of the oven door to prevent microwave leakage;
Industrial robot arm: Control the range of motion through the limit switch to avoid over-travel damage to the equipment;
Car door: Monitor whether the car door is closed tightly, and trigger an alarm when it is not closed.
3 Precision control and signal feedback
The micro-stroke (usually only a few millimeters) and precise trigger force of the micro switch make it suitable for precision instruments, such as:
Medical equipment: Detect the position or state of components;
Automotive electronics: Control seat adjustment, start button, etc.
Main application areas
Household appliances: water level control of rice cookers and washing machines, microwave oven door switches, etc.
Industrial automation: mechanical arm limit, conveyor belt control, safety door monitoring;
Automotive industry: start button, window lift, seat belt detection;
Military and aerospace: circuit control of missiles, tanks and other equipment.
Product features and selection
Life and materials: Mechanical life ranges from 30,000 to 10 million times, and high-end models use titanium alloy reeds to improve durability;
Environmental adaptability: Optional sealed or waterproof models are suitable for harsh industrial environments.
Summary: Although the micro switch is small in size, it has become an indispensable component in modern electronic equipment and industrial systems due to its fast response, high reliability and wide applicability.
