Claim:
1. An electrical contactor comprising: a first terminal connected to first and second fixed contacts on opposite faces of a fixed conductive member; a second terminal; a first movable arm of electrically conductive material connected to the second terminal, and carrying a first movable contact at a free end remote from the connection to the second terminal, the first movable contact and the first fixed contact forming a first switch and being arranged in a first switch pair; a second movable arm of electrically conductive material connected to the second terminal, and carrying a second movable contact at a free end remote from the connection to the second terminal, the second movable contact and the second fixed contact forming a second switch and being arranged in a second switch pair, wherein the contacts of the first switch pair of contacts are larger than the contacts of the second switch pair of contacts; and an actuating arrangement arranged to move the movable arms so as to open and close the switches, wherein the first movable arm and the second movable arm extend in a longitudinal direction, and the first movable arm includes a first sloping section, and the second movable arm includes a second sloping section, and the first sloping section of the first movable arm and the second sloping section of the second movable arm are offset from each other in the longitudinal direction, such that when the actuating arrangement moves to close the switches, the first switch pair of contacts closes before the second switch pair of contacts does.
