1. A switch assembly, comprising:
a first housing;
a plurality of key shifter levers, the key shifter levers each comprising a first end and a second end, a shaft pin being connected to the key shifter lever between the first end and the second end, the key shifter lever extending from the first end to the second end, and the key shifter lever being configured to pivot in a radial plane with the shaft pin as a center, wherein the second end extends to the outside of the first housing;
a second housing, the second housing surrounding the first end of the key shifter lever and having a first limiting surface located above the key shifter lever and a second limiting surface located below the key shifter lever;
a first push rod and a second push rod, the first push rod and the second push rod being arranged in the radial plane and respectively corresponding to the first limiting surface and the second limiting surface, and the first push rod and the second push rod leaning on the key shifter lever between the first end and the shaft pin, wherein at least one of the first push rod and the second push rod is always kept in contact with the first limiting surface or the second limiting surface by setting a dimension relationship; and
a first rubber pad and a second rubber pad, the first rubber pad and the second rubber pad respectively matching the first push rod and the second push rod, the first rubber pad being configured to push the first push rod toward the key shifter lever, and the second rubber pad being configured to push the second push rod toward the key shifter lever, wherein a second prepressure provided by the second rubber pad exceeds a predetermined value than a first prepressure provided by the first rubber pad.
