9. A relay contactor, comprising:
first and second pairs of leads;
a shaft assembly comprising a shaft, a plate disposed on the shaft and an elastic element, the shaft and the plate being movable between first and second positions relative to the first and second pairs of the leads, respectively;
first and second actuators coupled to the shaft at first and second sides of the plate, respectively, and configured to selectively move the shaft and the plate between the first and second positions in opposition to the elastic element; and
first and second bearing assemblies disposed to movably support the shaft at the first and second sides of the plate, respectively,
wherein the elastic element comprises a first elastic element anchored at opposite ends thereof to the first actuator and the shaft and a second elastic element anchored at opposite ends thereof to the second actuator and the shaft or the plate.
