The invention provides a car door outer side switch assembly which comprises a car door outer side wall, a handle body, a U-shaped limiting plate and two folding rods. The door body outer side wall isprovided with a handle groove capable of containing the handle body. The U-shaped limiting plate is fixed to one end of the handle groove. An acute angle is formed between the U-shaped limiting plateand the handle groove. When the handle body is turned over to the outside to the largest angle, the U-shaped limiting plate and the handle body abut against each other. The two folding rods are mutually hinged through a rotating shaft. The end portion of one folding rod is hinged to the inner wall of the handle groove, and the end portion of the other folding rod is hinged to the end portion of the handle body. The car door outer side switch assembly has the beneficial effects of being reasonable in structural design, conforming to the human engineering principle, being capable of effectivelyprotecting the key portion on a handle, and prolonging the service life.
