Contactor with heat transfer device

A contactor comprising:

• a housing having an outer wall defining a cavity, the housing having a first end and a second end opposite the first end;
• a switch assembly received in the cavity, the switch assembly including a first fixed contact received in the cavity and a second fixed contact received in the cavity, the switch assembly including a movable contact movable within the cavity between a mated position and an unmated position, the movable contact engaging the first and second fixed contacts to electrically connect the first and second fixed contacts in the mated position, the switch assembly including a coil assembly in the cavity operated to move the movable contact between the unmated position and the mating position;
• and
• a heat transfer device coupled to the housing, the heat transfer device including a cold plate having a coolant channel therethrough, the cold plate including a thermal interface thermally coupled to the first fixed contact and the second fixed contact to dissipate heat from the first fixed contact and the second fixed contact with aid of coolant fluid flowing through the coolant channel.
