Isolating switch

The utility model discloses an isolating switch, and particularly relates to the field of electric power, the isolating switch comprises an isolating switch, one side of the isolating switch is provided with a limiting mechanism, and the limiting mechanism comprises a connecting block, a rotating shaft, a switch blade, a spring, a limiting rod, a limiting groove, a scale bar and a fixing bolt. According to the utility model, through the arrangement of the limiting mechanism, in the using process of the isolating switch, the switch blade can be pulled firstly, under the action of the rotating shaft, the rotating shaft is utilized to drive the switch blade to rotate, and when the switch blade rotates, the limiting rod can be driven to enter the inner side of the limiting groove under the action of telescopic resetting of the spring, so that the isolating switch is prevented from being damaged. The limiting groove and the limiting rod are used for limiting the position of the switch blade, and the situation that
