The invention relates to a novel high-synchronism multi-contact travel switch which comprises a roller, a shell, a magnet and a static contact seat, a spring piece, a pressure spring, a movable contact seat and a push rod are packaged in the shell, the static contact seat is composed of a wiring terminal and a static contact, the movable contact seat is composed of a conducting strip and a movable contact, and the static contact is in contact connection with the movable contact. Compared with an existing travel switch with the same number of contacts, the travel switch has the advantages that the structure is simple, the performance is reliable, the synchronism of contact actions during switching is improved, the defects that part of contacts are switched and part of contacts are not switched when actions are in place are eliminated, and potential safety hazards generated in the use process of the travel switch are completely eradicated. 本发明涉及一种新型高同步性多触点行程开关，包含滚轮、壳体、磁铁、静触座，壳体内封装有弹簧片、压簧、动触座和推杆，静触座由接线端子和静触头组成，动
