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.
