A multipole disconnect switch comprising a plurality of stationary and movable electrical contacts, a stationary contact carrier for supporting the stationary contacts, a movable contact carrier for supporting the movable contacts, an operating handle movable between a first and a second position, and means responsive to the movement of the handle between the first and the second position for moving the movable contact carrier toward and away from the stationary contact carrier in a translatory manner to simultaneously close all contact sets when the handle is moved to the first position, and simultaneously open all contact sets when the handle is moved to the second position. Means is also provided for retaining a planar surface of the movable contact carrier parallel to the plane of an adjacent planar surface of the stationary contact carrier as the movable contacts move toward and into engagement with their respective stationary contacts in order to insure simultaneous closing of all contact sets. Means for insuring proper alignment of each movable contact with its respective stationary contact is also provided. This last mentioned means also includes provision for preventing assembly of the stationary and movable contact carriers while the operating handle is in the first position.
