    Abstract: In an embodiment, a multi-switch contactor assembly includes an array of at least three switches, the array including a first switch comprising a first moveable contact and at least one first fixed contact, the first switch configured to change a switch state between an open state and a closed state; a second switch comprising a second moveable contact and at least one fixed second contact, the second switch configured to change a switch state between an open state and a closed state; and a third switch comprising a third moveable contact and at least one third fixed contact, the third switch configured to change a switch state between an open state and a closed state. The multi-switch contactor assembly further includes an actuator assembly configured to actuate the first moveable contact, the second moveable contact, and the third moveable contact, the actuator assembly including a shaft, wherein the respective switch states of the three switches is change in dependence upon rotation of the shaft.

    Abstract: Methods and apparatuses for failure mode detection in a contactor are disclosed. In a particular embodiment, a method for failure mode detection in a contactor includes maintaining the contactor command signal in the open state; connecting the contactor to a voltage supply that supplies a first predetermined voltage amount to the contactor; measuring a first amount of time for a magnitude of a coil current of the coil to exceed a first predetermined current threshold; determining whether the first amount of time exceeds a first predetermined time threshold; responsive to determining that the first amount of time does not exceed the first predetermined time threshold, determining that the contactor is in the open state; and responsive to determining that the first amount of time exceeds the first predetermined time threshold, determining that the contactor is in the closed state.
