The invention relates to a bistable travel switch device which comprises a travel switch and a pair of switch knives, the travel switch is installed on the inner wall of a shaft, and the two switch knives are installed on the two sides of the end, close to the inner wall of the shaft where the travel switch is located, of a lift car respectively; the travel switch comprises a hollow shell and a connecting rod assembly with one end rotationally connected with the shell, and a roller is arranged at the other end of the connecting rod assembly. Two static contacts are fixedly arranged in the shell, the part, located in the shell, of the connecting rod assembly is fixedly connected with a driving block, and the two ends of the driving block are connected with two movable contacts respectively. A holding device is further arranged in the shell and used for limiting rotation of the connecting rod assembly and enabling the connecting rod assembly to be kept at two preset positions, when the connecting rod assembly is located at one of the preset positions, one set of movable contacts and static contacts are connected through movement of the driving block, and when the connecting rod assembly is located at the other preset position, the other set of movable contacts and static contacts are connected through movement of the driving block. And the other group of movable contacts are connected with the static contacts through the movement of the driving block.
本发明涉及一种双稳态行程开关装置,包括:行程开关与一对开关刀,所述行程开关安装于井道内壁,两所述开关刀分别安装在轿厢靠近行程开关所在井道内壁一端的两侧;行程开关包括中空的壳体以及一端与壳体转动连接的连杆组件,连杆组件的另一端设置有滚轮;所述壳体内固定设置有两静触点,所述连杆组件位于壳体内的部分固定连接有驱动块,所述驱动块的两端分别连接有两动触点;壳体内还设置有保持装置,用于限制连杆组件的转动并使连杆组件保持在两预设的位置,当连杆组件在预设的其中一个位置时,其中一组动触点与静触点通过驱动块移动相接通,当连杆组件在预设的另一个位置时,另一组动触点与静触点通过驱动块移动相接通。
