Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
The specific embodiment of switch of the present utility model, as shown in Figures 2 to 4, the switch are a breaker, the breaker
Including support, vacuum interrupter 8, the action-changing device of insulated tension pole 1 for driving the divide-shut brake of vacuum interrupter 8 and driving
The drive mechanism of the device（Not shown in figure）, wherein insulated tension pole 1 action-changing device includes extending above and below axis direction
Insulated tension pole 1 and connecting lever 3.Wherein the upper end of insulated tension pole 1 is fixedly connected with vacuum interrupter 8, and insulated tension pole 1 can be with push-and-pull
The moving contact of vacuum interrupter 8 realizes the divide-shut brake of arc-chutes；The lower end of insulated tension pole 1 is connected with contiguous block 2, and passes through connection
Block 2 and connecting lever 3 are hinged, during connecting lever 3 is rotated, can drive and be moved under the in the vertical direction of insulated tension pole 1.
Connecting lever 3 is arranged at intervals by two support chips and is fixed together with connecting shaft 9, and connecting shaft 9 is fixed on support, wherein driving
