Switch technical Characteristics

Switch application: widely used in various household appliances, electronic equipment, automation equipment, communication equipment, automotive electronics, power tools and other fields.

Different types of micro switches

A micro switch is a contact mechanism that has a small contact interval and a snap-action mechanism, and uses a specified stroke and a specified force to switch the contact mechanism. It is covered by a shell and has a drive rod outside of it. Southeast Electronics will introduce the different types of micro switches below.

The external mechanical force of the micro switch acts on the action reed through the transmission elements (press pins, buttons, levers, rollers, etc.). When the action reed is displaced to the critical point, it will produce instantaneous action, making the moving contact at the end of the action reed. Quickly connect or disconnect with fixed contacts.
When the force on the transmission element of the micro switch is removed, the action reed produces 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 instantaneously completed. The contact distance of the micro switch is small, the action stroke is short, the pressing force is small, and the on-off is rapid. The movement speed of the moving contact has nothing to do with the movement speed of the transmission element.

There are many types of micro switches, and there are hundreds of internal structures. They are divided into ordinary, small and ultra-small according to the volume; according to the protection performance, they are divided into waterproof, dustproof, and explosion-proof; according to the breaking form, there are single-connection Type, double type, multi-connected type. At present, there is also a strong disconnection micro switch (when the reed of the switch does not work, the external force can also make the switch disconnect).

Micro switches are classified into ordinary type, DC type, micro current type, and high current type according to their breaking capacity. According to the use environment, there are ordinary type, high temperature resistant type (250℃), super high temperature resistant ceramic type (400℃). The basic type of micro switch is generally without auxiliary pressing attachment, and derives small stroke type and large stroke type. Different auxiliary pressing accessories can be added according to the needs. According to the different pressing accessories added, the switch can be divided into various forms such as button type, reed roller type, lever roller type, short boom type, long boom type, etc.
