A contact system includes at least one first contact (4), at least one second contact (1), and at least one movable contact (3). A coil (12) is provided which, when energized generates a force. A magnet (9) is also provided, the magnet (9) having a magnetic force. The forces of the coil (12) and magnet (9) attract the at least one movable contact (3) to the at least one first contact (4). A return spring (8) having a spring force cooperates with the at least one movable contact (3) to return the at least one movable contact (3) to the at least one second contact (1) when the coil (12) is not energized. The sum of the forces applied by the coil (12) and the magnet (9) are sufficient to overcome the spring force of the return spring (8) to provide a balanced force to both the at least one second contact (1) and the at least one first contact (4).

A latch (16) for securing a connector to a device comprises a body (46) including a hub (50), an actuator (48) extending from the hub, a latch pin (52) extending from the hub, and a return spring (64). The latch pin is configured to be moved between a latched position wherein the connector is secured to the device, and an unlatched position wherein the connector is separable from the device. The actuator is configured such that movement of the actuator moves the latch pin between the latched position and the unlatched position, and the return spring is configured to bias the latch pin to the latched position. The hub, the actuator, the latch pin and the return spring are integrally formed such that the body is a single, unitary body.

A switch assembly adapted and a method for switching power to a circuit having a power source. The switch assembly includes current carrying contacts and a coupling member. The coupling member has conductive pads for engaging the current carrying contacts and a contact bridge extending between the conductive pads. An actuator assembly moves the coupling member between a closed position in which the conductive pads of the coupling member engage the current carrying contacts and an open position in which the conductive pads of the coupling member are disengaged from the current carrying contacts. Opposing electromagnetic forces are generated between the contact bridge and the conductive pads to resist electromagnetic repulsion forces generated between the current carrying contacts and the conductive pads as the actuator assembly approaches or is in the closed position.
