The present application relates to elevator safety technology, and in particular to a device for detecting a function of a contactor and elevator functionality device comprising the device. According to an aspect of the present application, there is provided a device for detecting a function of a contactor, wherein the contactor is configured to short three-phase phase lines of an elevator motor together by closing contacts, the device comprising: a voltage signal source coupled with the contactor; a voltage detection unit coupled with the three-phase phase lines of the elevator motor; a switching unit arranged between the contactor and the voltage signal source and between the voltage detection unit and the three-phase phase lines, wherein, in a detection mode, the switching unit is configured to conduct the voltage signal source to the contactor to provide a voltage detection signal to the three-phase phase lines via the contactor and to conduct the voltage detection unit to the three-phase phase lines, the voltage detection unit being configured to measure voltage of the three-phase phase lines and to output measurement to a control unit.
