The invention relates to a contact switch of an elevator. The contact switch comprises a base arranged on an elevator frame, a rotating portion arranged on the base in a rotating mode, a torsional spring for enabling the rotating portion to return to the original state by the rotating portion, a contact strip arranged on the rotating portion and a contact head arranged at one end of the contact strip, wherein the contact strip is provided with a strip-shaped through groove in the length direction of the contact strip. The contract switch further comprises a locking mechanism for locking the rotating portion and the contact strip in a relative mode. When the locking mechanism conducts locking, the rotating portion and the contact strip are fixed relatively; when the locking mechanism conducts unlocking, the contact strip can be arranged on the rotating portion in the mode of being capable of sliding along the strip-shaped through groove. According to the contact switch of the elevator, in match with the locking mechanism, the relative position of the contact strip and the rotating portion can be adjusted selectively so as to achieve the purpose that the contact switch can be used under multiple conditions, the universality of the contact switch is improved, and meanwhile, the contact switch is simple in structure and convenient to use.
