Abstract
The utility model relates to an isolating switch with a quick-action mechanism. The isolating switch comprises movable contact pieces with movable contacts, fixed contact pieces with fixed contacts, and an operation execution mechanism. The operation execution mechanism comprises a handle, a U-shaped pin, a U-shaped clamping sleeve, an energy storage spring, and a movable contact piece support. By arranging an elastic energy storage element, a support limiter, and a handle cam curved surface in a transmission mechanism, the movable contact piece support is limited in the middle of the process that the handle drives the movable contact piece support through the transmission mechanism to slide to close, thereby enabling the elastic energy storage element to compress and store energy. In the rear part of the process that the handle drives the movable contact piece support through the transmission mechanism to slide to close, the limit on the movable contact piece support is released so that the movable contact piece support can slide towards the fixed contact pieces under the effect of the elasticity of the elastic energy storage element at a speed substantially faster than a speed produced when the handle drives directly, thereby making the movable contacts contact with the fixed contacts quickly, shortening the contacting process, reducing the degree of the contact ablation, and prolonging the service life of the isolating switch.
