Abstract
The utility model relates to a single non-automatically-resetting type pressure relief switch, which comprises a positioning block, a conducting strip with a static contact, an upper elastic sheet, a lower elastic sheet and an insulating column. The positioning block, the conducting strip, the upper elastic sheet, the lower elastic sheet and the insulating column are connected in sequence through porcelain rings and porcelain tubes. The insulated column is provided with a self-locking elastic mechanism. The self-locking elastic mechanism comprises a movable contact sheet, an arched elastic sheet and a movable elastic sheet. One end of the movable contact sheet and one end of the movable elastic sheet are arranged on the insulated column and are connected with the upper elastic sheet. The bottom surface of the other end of the movable contact sheet is provided with a movable contact corresponding to the static contact. The two ends of the arched elastic sheet are respectively and movably connected with the movable contact sheet and the movable elastic sheet. According to the technical scheme of the utility model, due to the adoption of the elastic self-locking mechanism, when the pressure in a container reaches a highest required pressure value, the two contacts of the switch are always kept in a separated state and are incapable of resetting automatically. Therefore, the final-stage protection on the electrical pressure container is realized.
