Classification of microswitch

Classification of microswitch

Microswitch is a kind of switch mechanism with small contact spacing and quick action, which uses specified stroke and specified force to switch. It is covered with a housing with a drive lever on the outside. Because the contact spacing of the switch is relatively small, it is named micro switch, also known as sensitive switch.

Also known as sensitive switch and quick switch. Pressure driven fast opening and closing. Used for door switches in anti-theft systems.

Classification of microswitch

There are many kinds of microswitches, with hundreds of internal configurations. According to the size, there are ordinary, small, super small. According to the protective performance, there are waterproof, dustproof, explosion-proof; According to the form of disconnection, there are single - connected, double - connected and multi - connected.

There is also a strong disconnect microswitch (when the switch reed does not work, the external force can also turn off the switch); According to the breaking capacity, there are ordinary type, DC type, micro current type and high current type.

According to the use of the environment, there are ordinary type, high temperature resistant type (250℃) and ultra high temperature resistant ceramic type (400℃).

General micro switch is based on the accessory without auxiliary press, derived from small stroke and large stroke. 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 arm type, long arm type and other forms.

The sizes are small, super small, super small and so on. The function is waterproof. A more common application is the mouse button.
