Problems solved by technology
Its shortcoming is: when producing disc-shaped shrapnel, its thickness and the height of the convex surface determine the size of the pressure and pressure difference. After the product is finalized, it cannot be adjusted again. The contact points are prone to sparks, poor contact, and the disconnection distance is not enough, which cannot meet the requirements for adjusting pressure and pressure difference in large and medium-sized pressure switches. Tens of thousands of times, affecting switch stability and service life
Due to the need to adjust the pressure difference, the existing large and medium-sized switches have a service life of 200,000 times, so multiple sets of springs and metal parts are required to cooperate, which is very heavy and expensive to manufacture

The automatic pressure switch comprises a connection body, a dish-shaped spring sheet, a switch pedestal, a wiring frame, a dish-shaped spring sheet spring, a dish-shaped spring sheet spring lower base, a pressure spring and a differential pressure spring. The automatic pressure switch is characterized in that the dish-shaped spring sheet is arranged on the upper end face of the dish-shaped spring sheet spring and the protruding section of the dish-shaped spring sheet is downward and arranged on the upper end face of the dish-shaped spring sheet spring. The dish-shaped spring sheet spring lower base is arranged at the lower part of the dish-shaped spring sheet spring. The pressure spring is arranged in the switch pedestal, one end is placed above the dish-shaped spring sheet spring lower base and the other end is a pressure adjusting nut. The differential pressure spring is arranged in the wiring frame. The upper part is a differential pressure adjusting nut, and the lower part is pressed on a differential pressure ejector pin. The lower part of the differential pressure ejector pin is located above the recessed surface of the dish-shaped spring sheet and does not contact the recessed surface. During usage, by utilization of cooperation usage of the dish-shaped spring sheet spring, the automatic pressure switch can meet usage requirements of various automatic pressure switches medium and small sizes, and the manufacturing cost is low.
Description
Technical field [0001] The invention relates to a pressure switch, in particular to a disc-shaped elastic sheet automatic pressure switch. Background technique [0002] The existing automatic pressure switch with disc-shaped shrapnel relies on pressure to push the disc-shaped shrapnel. When the disc-shaped shrapnel receives a certain pressure, the convex surface deforms and pushes the thimble, and the thimble pushes the shrapnel to disconnect the contact point and the switch is disconnected; the pressure disappears or When it is reduced to a certain value, the protruding surface of the dish-shaped shrapnel returns to position, and the shrapnel pushes the thimble to return to drive the contact point to return and the switch is closed. Its shortcomings are: in the production of dish-shaped shrapnel, its thickness and convex surface determine the pressure and pressure difference. After the product is shaped, it cannot be adjusted. The convex surface of the dish-shaped shrapnel canno...
