Abstract
An operating mechanism for a centrifugal switch contains at least: a terminal box, a cover, a movable contact, a static contact, a swing arm, a reset elastic part, and a shifting fork. The movable contact and the static contact are disposed in the terminal box. The shifting fork operates to drive the swing arm to horizontally swing, whereby pushing the movable contact and implementing connection and disconnection between the movable contact and the static contact. The reset elastic part operates to automatically reset the shifting fork and the swing arm. The invention features reduced requirements for dimensional precision and installation precision of components, and low production cost, and is reliable and durable. In addition, the sliding force is uniformly stressed, which ensures accuracy of operation, easy installation, and high operating reliability.
