The contact assembly includes movable contacts (12), stationary contacts (11) and a movable contact bridge (17), where the movable contacts (12) are adapted to move towards or away from the stationary contacts (11) under the driving of the movable contact bridge (17). The auxiliary contact assembly includes an auxiliary contact bridge and auxiliary contacts (16), where at least portion of each of the auxiliary contacts (16) extends into the housing (13), and the auxiliary contact bridge moves synchronously with the movable contact bridge (17) to be selectively and electrically connected to the auxiliary contacts (16). The housing (13) includes a top surface and stepped portions (132). The top surface is spaced apart from the stepped portion (132) in the movement direction of the movable contact bridge (17) or the auxiliary contact bridge. The stationary contacts (11) are arranged on the top surface of the housing (13), and a portion of each of the auxiliary contacts 16 arranged outside the housing (13) is arranged on each of the stepped portions (132).
