The invention discloses a switch device for an elevator pit. The switch device comprises a plurality of switches, a stepping replacement mechanism and a switch selection loop. The switches are installed on a stepping replacement mechanism, the stepping replacement mechanism is used for switching the positions of the multiple switches so that one of the switches can be kept at a working position, and the working position refers to that when a beating plate fixed to a pit component moves downwards to a triggering position, the switch can be triggered to act, and an elevator safety circuit is disconnected; and the switch selection loop can enable the switch at the working position to be connected into the elevator safety loop and enable the other switches not to be connected into the elevator safety loop.
本发明公开了一种用于电梯底坑的开关装置,包括多个开关,步进更换机构和开关选择回路;所述开关安装在步进更换机构上,所述步进更换机构用于切换多个开关的位置,使所述开关中的一个保持在工作位置,所述工作位置是指当固定在底坑部件上的打板向下运动至触发位置时能够触发所述开关动作,使电梯安全回路断开;所述开关选择回路可使处于工作位置的开关接入电梯安全回路,使其余开关不接入电梯安全回路。
