Although the micro switch is not big, it plays an irreplaceable role in our daily life, and completes automatic control and safety maintenance in facilities where the power circuit must be replaced frequently. At this stage, it has been widely used in electronic products, instrumentation equipment, mining, power supply systems, electrical products and machinery and equipment, aerospace, aviation, cruise missiles, heavy tanks and other defense industries. In addition, it can also be used in electronic computer computer mouse, vehicle computer mouse, automotive electronic products, communication equipment, military products, equipment, natural gas water heaters, gas stoves, small electrical appliances, microwave heating, rice cookers, water pump pressure Switching machinery and equipment, medical equipment, engineering and building automation technology, pneumatic tools and general electrical equipment and wireless machinery and equipment, 24-hour timers.
The micro switch is a quick switch driven by working pressure, also known as a smart power switch. With the action spring, the kinetic energy is accumulated to the zero boundary point, resulting in an instantaneous action, so that the movable contact and the fixed and fixed contact at the end of the action spring are connected or disconnected. When the force on the components of the transmission system moves, the action spring causes the action force in the opposite direction. When the components of the transmission system reach the zero point of the action of the spring, the action in the opposite direction is immediately performed. The micro-switch contact interval is small, the action stroke is short, the driving force is small, and the breaking is fast. The action efficiency of its action contact is irrelevant to the action rate of the transmission system components. The micro switch is basically based on the market type, and can be derived from short stroke, large stroke, large stroke, large stroke, large stroke, roller buttons, spring rollers, lever rollers, short arms, excavator extended arms, etc. Micro switches are used for automatic control systems and repeated replacement of electronic products and other facilities. Micro switches are divided into large and medium-sized, medium-sized and small. According to different needs, it can be divided into moisture-proof type (for liquid environment) and general-purpose type. The power switch connects two wires and provides plug-in and power-off control for household appliances and equipment.
