A high load switch for a vehicle includes a case having an opening formed at an upper side of the case; a first contact unit disposed at a lower side in the case; a second contact unit disposed at a lower side in the case and disposed directly above the first contact unit; and a contactor having one end fixed to one side in the case, and the other end disposed between the first contact unit and the second contact unit, in which a portion of the contactor between the one end and the other end is continuously formed, and the contactor includes a pusher unit formed by being bent upward so that an intermediate portion thereof penetrates the opening and protrudes, and a reinforcement bead formed on a surface of the contactor, thereby preventing deformation in the contactor and enhancing durability.
