This utility model discloses a micro switch, including a main body with a receiving cavity, in which a moving contact and a stationary contact are disposed. It also includes a triggering assembly for triggering the movement of the moving contact. The triggering assembly includes an elastic connector, a contact rod, a trigger plate, and a hinge. The contact rod and the trigger plate are respectively assembled at both ends of the connector, forming a lever structure. The hinge is rotatably configured and connects the moving contact and the trigger plate. Through the cooperation of the lever structure, when the contact rod is subjected to an action force, the contact rod drives the connector to undergo a slight deformation, which in turn drives the trigger plate to rotate. The trigger plate triggers the hinge to rotate, thereby causing the moving contact to abut against or move away from the stationary contact. This achieves the triggering of the switch by the micro-movement of the contact rod, based on the principle of amplifying the triggering stroke using a lever structure. It can also replace the existing plunger structure and achieve rapid triggering.
