Description

Technical Field

[0001] The utility model relates to the technical field of vehicle switches, in particular to a handle assembly of a steering column shift switch. Background Art

[0002] There are two types of gear lever arrangements for vehicles: floor shift and steering column shift. When the vehicle gear lever is located at the lower right of the steering wheel, it is called a steering column shift. Although the handle of the existing steering column shift is provided with characters indicating the gear positions, after the gear is switched, the backlight color state of the characters does not change accordingly, and it is impossible to indicate the current gear position, which is inconvenient for the operator to identify. In addition, the buttons on the handle of the existing vehicle steering column shift switch are usually connected by springs, which can make the elasticity of the buttons full. However, since the springs are made of metal, the springs will rub against the side walls of the chambers accommodating the springs during the pressing process, resulting in noise. Summary of the Invention
