Abstract: A contactor (1) comprising a first contact member (3) fixed and connected to a first conductor (5) of an electrical circuit; a second contact member (7) connected to a second conductor (9) of the electrical circuit by a connector (11); wherein the second contact member moves between a break position, in which the first and second contact members are out of contact, and a make position, in which the first and second contact members are in contact; an actuator assembly (15) coupled to the second contact member such that actuation of the actuator assembly translates into movement of the second contact member; an electromagnetic arrangement comprising an electromagnetic coil (17) and at least a part of the actuator assembly, wherein, when the coil is energised, the coil generates a magnetic field and thereby the actuation assembly is caused to move under the influence of the magnetic field, which in turn causes the second contact member to move; a hermetically sealable enclosure (2); wherein the first and second contact members, the connector, and the actuation assembly are inside the enclosure; and the coil is outside the enclosure.
