Micro switch picture_ Micro switch working principle overview
The micro switch is a contact mechanism with a small contact interval and a snap action mechanism, and the switch action is performed with a specified stroke and a specified force. It is covered with a shell and has a drive rod outside. A kind of switch, because the contact distance of the switch is relatively small, it is called a micro switch, also known as a sensitive switch and a snap switch. Pressure actuated quick switch.

The micro switch is a contact mechanism with a small contact interval and a snap action mechanism, and the switch action is performed with a specified stroke and a specified force. It is covered with a shell and has a drive rod outside. A kind of switch, because the contact distance of the switch is relatively small, it is called a micro switch, also known as a sensitive switch and a snap switch. Pressure actuated quick switch. For door switches in anti-theft systems, etc. There are many types of micro switches, and there are hundreds of internal structures. According to the volume, there are ordinary, small, and ultra-small; according to the protection performance, there are waterproof, dust-proof, and explosion-proof types; according to the breaking form, there are Single type, double type, multi-link type.
How microswitches work
The external mechanical force acts on the action reed through transmission elements (pressing pins, buttons, levers, rollers, etc.). Instantaneous action occurs when the action reed is displaced to a critical point. The moving contact and the fixed contact at the end of the action reed are quickly connected or disconnected. When the force on the transmission element is removed. The action reed produces the opposite action force. When the reverse stroke of the transmission element reaches the critical point of action of the reed. The reverse action is completed instantaneously. The contact distance of the micro switch is short, and the action stroke is short, and the on-off is fast according to the power. The action speed of the moving contact has nothing to do with the action speed of the transmission element.
