The invention discloses an elevator roller switch which comprises a shell, the bottom of the shell is connected with a roller support through a rotating shaft, rollers are installed at the two ends of the roller support, a static contact is installed on the upper portion of the end, away from the rotating shaft, in the shell, and a spring is vertically arranged in the shell. The lower end of the spring is connected with a guide rod, the guide rod vertically penetrates through a guide hole in the shell to be rotationally connected with one end of the roller support, and a through opening penetrating left and right is formed in the middle of the guide rod. And the elastic sheet transversely penetrates through the through opening, a first end of the elastic sheet is provided with a movable contact which is used for being in contact with the static contact, and a second end of the elastic sheet is fixedly connected with the shell. The roller switch can solve the problems that the contact stroke of a contact is not stable and a spring is easy to fall off due to the fact that an existing roller switch adopts a swing arm as a part driven by an elastic piece.

    本发明公开了一种电梯滚轮开关,包括壳体,所述的壳体的底部通过转轴连接有滚轮支架,所述的滚轮支架的两端均安装有滚轮,所述的壳体内部远离转轴的一端上部安装有静触点,所述的壳体的内部竖向设置有弹簧,所述的弹簧的下端连接有导向杆,所述的导向杆竖向穿过壳体上的导向孔与滚轮支架的一端转动相连,所述的导向杆的中部设置有左右贯穿的通口;弹片,从所述通口中横向穿过,所述的弹片的第一端设置有用于与静触点相接触的动触点,所述的弹片的第二端与壳体连接固定。本发明可以解决现有的滚轮开关采用摆臂作为弹片驱动的部件带来的触点接触行程不稳定、弹簧容易脱出的问题。
