The elastic force between the first pushing rod and the elastic base is larger than the operating force of the first switch contact, and the elastic force between the second pushing rod and the elastic base is larger than the operating force of the second switch contact.
The first locating piece is used for limiting the first displacement of the first switch assembly, and the second locating piece is used for limiting the second displacement of the second switch assembly.
In a working scene, when the sensor push rod receives low pressure, the sensor push rod drives the elastic piece to abut against the first switch assembly so as to drive the first switch assembly to move, after the sensor push rod moves to the first displacement, the first switch assembly abuts against the first positioning piece, and the first push rod drives the first switch contact to move inwards to trigger the first switch contact.
