The invention provides a travel switch for an elevator and a hoistway switch component. The travel switch comprises a casing, a fixed contact component fixed on the casing, a wiring seat fixed at one outer end of the casing, a twisting rod fixed on the casing, a twisting axle connected with one end of the twisting rod, and a twisting wheel connected with the other end of the twisting rod, wherein the twisting wheel is arranged on the twisting axle; a fixing seat is fixedly arranged on a twisting shaft; a torsion spring is arranged in the fixing seat and sleeves the twisting shaft; a movable contact component is also fixed on the fixing seat; the fixed contact component comprises a static contact piece; the static contact piece is fixed on the upper surface of the casing; the movable contact component comprises two movable contact pieces which are both arranged on the side, far away from the upper surface of the casing, of the static contact piece symmetrically; a position control device is also arranged at one end, on the casing, of the twisting rod. The travel switch and the hoistway switch component have the advantages that the connection between the contact components is improved and simplified, so as to reduce the size of the travel switch; the whole position control device is unique in design, thereby achieving an excellent spacing effect.
