The micro switch is a switch with a small contact interval and a snap-action mechanism, which is switched with a specified stroke and a specified force. It is covered with a casing and has a drive rod on the outside. Because the contact distance of the switch is relatively small, it is named as a micro switch, also known as a sensitive switch. Apply pressure to actuate the quick switch. For door switches in anti-theft systems, etc.
A micro switch, as the name suggests, is a switch with a small force. It is a switch in which the external mechanical force acts on the action reed through the transmission element, so that the fixed contact at the end and the moving contact are quickly connected or disconnected.
The micro switch has a small contact interval and a contact mechanism of a snap-action mechanism, and performs the switching action with a specified stroke and force.
Micro switches are composed of five categories of constituent elements. The contact distance is small and the torque is large. Usually there are drive rods on the outside.
The external force acts on the action reed through transmission elements (press pins, buttons, levers, rollers, etc.). ), and when the action reed moves to the critical point, an instantaneous action is generated, which makes the moving contact and the fixed contact at the end of the action reed quickly connect or disconnect.
When the acting force on the transmission element is eliminated, the acting reed generates a reverse force, and when the reverse stroke of the transmission element reaches the critical point of the action of the reed, the reverse action is completed instantly.
The advantages of the micro switch are that the contact distance is small, the movement stroke is short, the pressing force is small, and the on-off is fast. The moving speed of the moving contact has nothing to do with the moving speed of the transmission element.
