Electric drawable component position locking device

The utility model provides an electric drawable component position locking device and belongs to the technical field of electrical devices. The device comprises a control loop of a first electric drawable component and a first auxiliary contact S2 used for being matched with a second electric drawable component, and is characterized in that the first auxiliary contact S2 matched with the second electric drawable component is serially connected in the control loop of the first electric drawable component The device has the advantages that by utilizing the requirement that the position state auxiliary switches of the drawable components must operate when the drawable components are switched to be in place at a test position and a working position, the position state auxiliary switches penetrate into the control loops of the other drawable components, so that logical operation sequence of multiple electric drawable components can be realized, not only can the power distribution reliability be ensured, but also misoperation can be avoided, and the device is simple in structure and low in cost.
