Small micro switch is a contact mechanism with small contact spacing and fast braking mechanism, which operates with the specified stroke and force. It is covered by the shell, and its external is a switch with a driving rod. Because its contact spacing is small, it is also called micro switch, also known as sensitive switch, etc.
There are many kinds of small micro switches, and there are hundreds of internal structures. According to the volume division method, there are ordinary type, small type and ultra small type; According to the protection performance method, there are waterproof type, dust type and explosion-proof type; According to the form of open circuit, there are single connection, double connection and multiple connection.
In addition, the disconnection function of small microswitch (when the reed of the switch does not work, the switch can be disconnected by external force) is also very strong; According to the breaking capacity, there are ordinary type, DC type, micro flow type and large flow type.
It can be divided into ordinary type, high temperature resistant type (250 ℃) and ultra high temperature resistant ceramic type (400 ℃)
The basic type of small micro switch is generally without auxiliary press accessories, and small line program and large line program are derived. Different auxiliary pressing devices are equipped as required. The switches equipped with the auxiliary pressing device can be divided into button type, spring roller, lever roller, short boom, long boom and other forms.
The size of small microswitch includes small, ultra small, ultra small, etc. The function is waterproof. The most commonly used application is the mouse button.
Generally, the size is 27.8 long, 10.3 wide and 15.9 high, and the parameters vary with large capacity and small load.
The general size is 19.8 long and 6.5 wide, with high precision and high service life of different properties.
Ultra small microswitch.
The general size is 12.8 long, 5.8 wide and 6.5 high. This model has a special thin design.
Small microswitches carry out automatic control and safety protection in the equipment that needs frequent circuit replacement. They have been widely used in electronic equipment, instruments and meters, mines, power systems, household appliances, electronic equipment, aerospace, aviation, ships, missiles, tanks and other military fields. Although the switch is small, it plays an irreplaceable role.
The reed of small micro switch is made of rare metal titanium.
Suitable for computer mouse, automobile mouse, automobile electronics, communication equipment, military products, tester, gas water heater, gas stove, small household appliances, microwave oven, electric rice cooker, floating ball equipment, medical equipment, building automation, electric tools, general electric and wireless equipment, 24-hour timer, etc.
