What is a micro switch
The micro switch is a contact mechanism with a small contact interval and a snap-action mechanism, and a contact mechanism that performs the switching action with a specified stroke and a specified force. Small, hence the name micro switch, also called sensitive switch. The electrical text symbol is: SM.
Micro switch
There are many types of micro switches, and there are hundreds of internal structures. According to the volume, there are ordinary, small, and ultra-small; according to the protection performance, there are waterproof, dust-proof, and explosion-proof types; Single type, double type, multi-link type. There is also a strong disconnect micro switch (when the reed of the switch does not work, the external force can also make the switch disconnect); according to the breaking capacity, there are ordinary type, DC type, micro-current type, and high-current type. According to the use environment, there are ordinary type, high temperature resistant type (250℃), super high temperature resistant ceramic type (400℃)
Micro switches are generally based on unassisted pressing accessories as the basic type, and small stroke types and large stroke types are derived. Different auxiliary pressing accessories can be added according to the needs. According to the different pressing accessories added, the switches can be divided into various forms such as button type, reed roller type, lever roller type, short boom type, long boom type and so on.
Micro switches are used for automatic control and safety protection in equipment that requires frequent circuit switching, and are widely used in electronic equipment, instrumentation, mining, power systems, household appliances, electrical equipment, as well as aerospace, aviation, ships, missiles, Military fields such as tanks have been widely used in the above fields. Although the switch is small, it plays an irreplaceable role.
At present, the micro switches on the domestic market have different mechanical lifespans ranging from 3W times to 1000W times according to different use requirements. Generally, there are 10W times, 20W times, 50W times, 100W times, 300W times, 500W times and 800W times, which are generally used in China. Beryllium bronze, tin bronze and stainless steel wire are used as reeds. Foreign ALPS can achieve up to 1000W times. Their reeds are made of rare metal titanium. The WK-01B produced by Tengfei Electronics in China can reach up to 1000W times.
What are the microswitches for
The external mechanical force acts on the action reed through transmission elements (pressing pins, buttons, levers, rollers, etc.), and when the action reed is displaced to the critical point, an instantaneous action occurs, making the moving contact at the end of the action reed and the fixed contact point to switch on or off quickly.
When the force on the transmission element is removed, the action reed generates a reverse action force. When the reverse stroke of the transmission element reaches the critical point of the action of the reed, the reverse action is completed instantaneously. The contact distance of the micro switch is small, the action stroke is short, the pressing power is small, and the on-off is fast. The action speed of the moving contact has nothing to do with the action speed of the transmission element.
Mainly used in the switches of some electrical components, such as computer mouse, car mouse, automotive electronic products, communication equipment, military products, testing instruments, gas water heaters, gas stoves, small household appliances, microwave ovens, rice cookers, floating ball equipment, Medical devices, building automation, power tools and general electrical and radio equipment, 24-hour timers, etc.
