The invention discloses an elevator switch monitoring device. An illustrative example embodiment of a switch monitoring device includes a controller configured to command a switch into at least one of a conductive state and a non-conductive state. A monitoring circuit conducts current when the switch is in the conducting state. A comparator provides an output indicative of a relationship between a voltage of a selected portion of the monitoring circuit and a threshold voltage. A controller determines a condition of the switch based on a command and an output of the comparator.

    本公开的发明名称为“电梯开关监测装置”。一种开关监测装置的说明性示例实施例包括被配置成命令开关进入传导状态和非传导状态中的至少一个的控制器。当所述开关处于所述传导状态时监测电路传导电流。比较器提供指示所述监测电路的所选部分的电压和阈值电压之间的关系的输出。控制器基于命令和所述比较器的输出来确定所述开关的状况。
