The invention discloses a three-switch linkage pressing mechanism capable of resetting automatically. The lower end of a support is provided with a microswitch, and the side surface of the microswitch is provided with an angle sheet. The upper end of the support is inserted into the sleeve and screwed into the nut for connection. The upper end of the connecting rod is fixedly connected with the reset button. The lower end of the connecting rod is sleeved with the spring B and inserted into the sleeve. The upper end of the rack is sleeved with the gasket and screwed into the button head. The middle of the rack is sleeved with the spring A and inserted into the support. The lower end of the rack is inserted into the angle sheet on the side of the microswitch; and a short spring plunger is mounted in the middle of the rack, a rocker panel is placed behind the support, screws are screwed into the two ends of the support respectively to be hinged, and the two ends of a spring B are hung on the cotter pin and the rocker panel respectively. The mechanism is small in size, compact in structure, convenient to disassemble and assemble and high in reliability.
