Construction and application fields of micro switches

Share This Post

The micro switch is a contact mechanism with a small contact interval and a snap-action mechanism, which uses a specified stroke and a specified force to perform the switching action. It is covered with a shell and has a drive rod outside. Relatively small, hence the name micro switch, also known as sensitive switch. The electrical text symbol is: SM.

Widely used in electronic equipment, instrumentation, mining, power systems, household appliances, electrical equipment, and aerospace, aviation, ships, missiles, tanks and other military fields.

There are many kinds of micro switches, and there are hundreds of internal structures.

By volume

There are ordinary, small, ultra-small;

According to the protection performance,

There are waterproof type, dustproof type, explosion-proof type;

According to the split form,

There are single type, double type and multi-link type.

According to the breaking capacity,

There are ordinary type, DC type, micro-current type, high-current type.

According to the use environment,

There are ordinary type, high temperature resistant type (250 ℃), super high temperature resistant ceramic type (400 ℃).

At present, 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);

Micro switches are generally based on unassisted pressing accessories, 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.
