Gear separation piece and prevent switch of maloperation

The utility model provides a gear separation piece acts on the switch, the switch includes operating handle, gear separation piece sets up in the third position, the third position is located betweenthe primary importance and the second place of switch over travel. And simultaneously, the utility model also discloses a switch that has used the maloperation of preventing of above gear separation piece. Use the stroke position that this technical scheme can realize the limiting operation handle, restriction dependent manual operation to limit switch's state. Reach the mesh that provides dual safety guarantee for engineering service personnel and load. 本实用新型提供了种档位阻隔件作用于开关，所述开关包括操作手柄；所述档位阻隔件设置于第三位置，所述第三位置位于开关行程的第位置与第二位置之间。同时，本实用新型还公开了种应用了以上档位阻隔件的防误操作的开关。应用本技术方案可实现限制操作手柄的行程位置，限制人力操作，从而限制开关的状态。达到为工程维护人员和负载提供双重安全保障的目的。
