Abstract
The utility model discloses a three-position switch for a combined electric appliance. The three-position switch comprises a housing, basin-type insulators, an insulated rod, an isolated switch static contact, an isolated switch moving contact, a moving contact support, a support base, a fan-shaped shift fork, a grounding moving contact and a grounding static contact, wherein one end of the insulated rod is fixedly connected to the housing and the other end of the insulated rod is connected with the shift fork in the moving contact support, the isolated switch static contact is fixedly connected to an upper basin-type insulator which is connected with the housing, and the grounding static contact is fixedly connected with the housing through the basin-type insulators. When the insulated rod rotates around a center line, the fan-shaped shift fork is driven to rotate, and an L-shaped groove on the fan-shaped shift fork drives pivot pins connected with the moving contacts to complete closing or opening actions of the moving contacts. The three-position switch utilizes the nearly L-shaped groove on the fan-shaped shift fork to change a rotary movement of the insulated rod into a linear movement of the moving contact, and has advantages of simple structure, relatively strong applicability, relatively small occupied space, easy realization and reliable performance.
