What are the classifications of Micro Switch?
There are many kinds of micro switches, with hundreds of internal structures. According to volume integration, there are ordinary type, small type and ultra small type. According to the protection performance, there are waterproof, dustproof and explosion-proof types. According to the breaking form, there are single connection type, double connection type and multi connection type.
There is also a strong disconnect micro switch (when the reed of the switch does not work, the external force can also disconnect the switch). According to breaking capacity, there are ordinary type, DC type, micro current type and high current type.
According to the service environment, there are ordinary type, high temperature resistant type (250 ℃) and ultra high temperature resistant ceramic type (400 ℃)
Micro switch generally takes no auxiliary press accessories as the basic type, and derives small line program and large line program. Different auxiliary pressing accessories can be added as required. According to the different pressing accessories added, the switch can be divided into button type, reed roller type, lever roller type, short boom type, long boom type and other forms.
In size, there are small Arm Lever Limit Switches, super small electrical micro switches, super small and so on. The function is waterproof. The most common application is the mouse button.
Micro switches used to regulate the flow of current in a circuit are called electrical switches, commonly referred to as tiny snap-action switches. Micro switches are frequently utilized in a variety of products, including industrial machinery, automobiles, appliances, and electrical equipment. Micro switches can manage both high and low current loads and are renowned for their compact size and dependability.
When a physical force, such as the push of a button or the movement of a lever, activates a micro switch, a spring-loaded lever that opens and shuts the switch contacts occurs. Typically constructed of metal, switch contacts are intended to create a strong electrical connection when they are closed.
Single-pole single-throw (SPST), single-pole double-throw (SPDT), double-pole single-throw (DPST), and double-pole double-throw are some of the different types of micro switches that are available (DPDT). The type of micro switch that is most appropriate for a given application depends on its unique requirements, including those for voltage and current, the kind of actuator required to activate the switch, and the switch's size and physical position.
Where are electric micro switches used?
Microswitches perform automatic control and safety protection in equipment requiring frequent circuit replacement. They are widely used in electronic equipment, instruments and meters, mines, power systems, household appliances, electrical equipment, aerospace, aviation, ships, missiles, tanks and other military fields. They have been widely used in the above fields. Although the switch is small, it plays an irreplaceable role.
At present, according to different application requirements, the mechanical life of microswitches on the domestic market ranges from 3W times to 1000W times, generally 10W, 20W, 50W, 100W times, 300W times, 500W times and 800W times. Beryllium bronze, tin bronze and stainless steel wire are generally used as springs in China. Alps abroad can achieve 1000W times at most. Their springs are made of rare metal titanium.
It can be used in computer mouse, automobile mouse, automobile electronic products, communication equipment, military products, test instruments, gas water heaters, gas stoves, small household appliances, microwave ovens, electric rice cookers, floating ball equipment, medical instruments, building automation, electric tools, general electrical and radio equipment, 24-hour timers, etc.
