Abstract
A contactor includes: at least one moveable contact mounted on a contact carrier; at least one stationary contact mounted on a housing; an electromagnet arranged to cause the contact carrier to move relative to the housing between a first position and a second position, and thus to cause the at least one moveable contact to travel from a contacts open position to a contacts closed position with respect to the at least one stationary contact; a sensor coupled to one of the contact carrier and the housing and arranged to detect an intermediate position, in between the first position and the second position, at which the housing and the contact carrier are located at a given moment in time as the contact carrier moves relative to the housing between the first position and the second position; and a controller connected to receive the signals from the sensor.
