The invention provides a travel switch used for an elevator and a well switching assembly thereof. The travel switch comprises a housing, a fixed contact assembly fixedly arranged on the housing, a wire connector fixed on one end out of the housing, a twisting rod fixed on the housing, a twisting axle connected with one end of the twisting rod, and a twisting wheel connected with the other end of the twisting rod. The twisting wheel is arranged on the twisting axle. A twisting shaft is fixedly provided with a fixing base. The fixing base is internally provided with a torsion spring, and the spring is sleeved on the twisting shaft. The fixing base is also fixedly provided with a movable contact assembly. The fixed contact assembly comprises a static contact piece. The movable contact assembly comprises two movable contact pieces. The two movable contact pieces are symmetrically distributed on a same side of the static contact piece, and are on the opposite surface of the static contact piece which is fixed on the upper surface of the housing. One end of the twisting rod on the housing is also provided with a position control device. The travel switch improves and simplifies connection relations between the contact assemblies, size of the travel switch used for an elevator is reduced, and the whole design of the position control device is clever, thereby achieving good limiting effect.
