Abstract: A contactor (12; 112; 120) comprises at least one moveable contact (48) mounted on a contact carrier (50); at least one stationary contact (46) mounted on a housing (20); an electromagnet (54, 56) 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 between a contacts open position and a contacts closed position with respect to the at least one stationary contact; a sensor (70) coupled to one of the contact carrier and the housing and configured 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 (91) connected to receive the signals from the sensor and configured to use the signals to monitor transition of the contact carrier between the first position and the second position.
