Switch technical Characteristics

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

Introduction of Micro Switch

Micro switches are used for automatic control and safety protection in equipment that requires frequent circuit switching. They are widely used in electronic equipment, instrumentation, mining, power systems, household appliances, electrical equipment, as well as aerospace, aviation, ships, missiles, and Military fields such as tanks have been widely used in the above fields.
Although the switch is small, it plays an irreplaceable role.

Micro Switch
On the reed, when the moving reed is displaced to the critical point, an instantaneous action is generated, so that the moving contact and the fixed contact at the end of the moving reed are quickly connected or disconnected.
When the force on the transmission element 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.

The micro switch has a small contact interval and a snap-action mechanism,
The contact mechanism that switches on and off with a prescribed stroke and prescribed force is covered with a casing,
A type of switch with a drive rod outside. Because the contact distance of the switch is relatively small, it is called a micro switch, also called a sensitive switch.

working principle
External mechanical force acts on the action through transmission elements (push pins, buttons, levers, rollers, etc.)
